Re: Install Hadoop 3.2.1 on Windows 10 Step by Step Guide
Hi Tim,
Just an update the previous issue (understanding you have fixed it but I'd like to post my findings here too just in case other people may be interested).
I've done the following steps to see if I can run Hadoop daemons without Administrator right.
Commands can start successfully without any errors.
Very interestingly, this time NodeManager can start successfully while ResourceManager cannot due to the following error:
For YARN tmp folder, I am configuring it as the following:
So I then tried the following steps:
This time the services all started successfully without any errors.
I can verify that through resource manager UI too:
So to summarize:
Hope the above helps.

Re: Install Hadoop 3.2.1 on Windows 10 Step by Step Guide
Hello,
I have been able to get around my need for admin it seems so far by changing my config so the tmp-nm folder is in my Documents versus in C drive directly in tmp.
However, it seems I still have some issues. Two of them seem to point to wrong version of winutils.exe. I am running windows 10 64 bit and am trying to get hadoop 3.2.1 running. One symtom of the wrong version is the repeated warning in Yarn node manager window over and over
WARN util.SysInfoWindows: Expected split length of sysInfo to be 11. Got 7
Another was the failure code of a job I submitted to insert data into a table from the hive prompt. Job details were found in the Hadoop cluster local UI
Application application_1589548856723_0001 failed 2 times due to AM Container for appattempt_1589548856723_0001_000002 exited with exitCode: 1639

[2020-05-15 09:53:23.831]Container exited with a non-zero exit code 1639.
Some sites have said these two issues are symtom of having the wrong winutils.exe.
I have some other issues I'll wait to post after I can get these fixed.
I have used the link in this article to get winutils.exe. I have also tried other winutils.exe's I find out there. However, for the other ones I've tried when trying to start yarn, in the yarn node manager window it is full of errors like
2020-05-15 10:12:16,444 ERROR util.SysInfoWindows: java.io.IOException: Cannot run program "C:\Users\XXX\Documents\Big-Data\Hadoop\hadoop-3.2.1\bin\winutils.exe": CreateProcess error=216, This version of %1 is not compatible with the version of Windows you're running. Check your computer's system information and then contact the software publisher
So those ones are worse - I can't even get yarn started with those due to that error.
So with the version I am using now I can get YARN to start although I get the warning about "WARN util.SysInfoWindows: Expected split length of sysInfo to be 11. Got 7" but the actual hive insert fails anyway...
Appreciate the help. How do I find or know if a winutil.exe is meant for windows 10 64 bit and Hadoop 3.2.1?
Re: Install Hadoop 3.2.1 on Windows 10 Step by Step Guide
Hi Tim,
In my computer, all the paths for HADDOP_HOME and JAVA_HOME are configured to a location without any space as I was worried that the spaces issue may cause problems in the applications.
That's also the reasons that most of Windows Hadoop installation guides recommend configuring them in a path that has no space. This is even more important for Hive installation.
So I think you are right the issue was due to the space in your environment variables.
JAVA_HOME environment variable is setup in the following folder:
%HADOOP_HOME%\etc\hadoop\hadoop-env.cmd
And also in Step 6 of this page, we've added class paths for JARs:
<configuration> <property> <name>mapreduce.framework.name</name> <value>yarn</value> </property> <property> <name>mapreduce.application.classpath</name> <value>%HADOOP_HOME%/share/hadoop/mapreduce/*,%HADOOP_HOME%/share/hadoop/mapreduce/lib/*,%HADOOP_HOME%/share/hadoop/common/*,%HADOOP_HOME%/share/hadoop/common/lib/*,%HADOOP_HOME%/share/hadoop/yarn/*,%HADOOP_HOME%/share/hadoop/yarn/lib/*,%HADOOP_HOME%/share/hadoop/hdfs/*,%HADOOP_HOME%/share/hadoop/hdfs/lib/*</value> </property> </configuration>You can try to change them to absolute values with double quotes to see if they work.
To save all the troubles, I would highly recommend getting Java available in a path without space or create a symbolic link to the Java folder in a location without space in the path.

'C:\Program' is not recognized as an internal or external command,
operable program or batch file.
I think I know what is happening but don't know how to fix. One of my first errors was in hadoop.config.xml where it was trying to check if not exist %JAVA_HOME%\bin\java.exe but the problem is in path : C:\program files\Java\jre8 -Please note this directory "program files" has a space in it. The result was that I had to modify hadoop.config.xml to put double quotes around the check - making it
if not exist "%JAVA_HOME%\bin\java.exe" . This resolved that problem. Then another place I had found issue was on this line
for /f "delims=" %%A in ('%JAVA% -Xmx32m %HADOOP_JAVA_PLATFORM_OPTS% -classpath "%CLASSPATH%" org.apache.hadoop.util.PlatformName') do set JAVA_PLATFORM=%%A
This was messing up too for similar reason - it was erroring with similar error since some values in the classpath list were C:\program files\... and once it hit the space it blew up. For this line of code I just remarked it - since my HADOOP_JAVA_PLATFORM_OPTS is empty - I am not sure what I would have done had HADOOP_JAVA_PLATFORM_OPTS been populated. In any case, these were preliminary issues and all dealt with the fact that C:\program files... path was causing issues due to space. Therefore when I saw this latest exception, I am assuming it too is hitting this at java path or some member of classpath that has the same... but not sure where to modify - how to work around.
As of 5/15 6:10pm EDT - this is my current issue - you may disregard the prior comments if you wish since they are resolved... Thanks
Re: Install Hadoop 3.2.1 on Windows 10 Step by Step Guide
Hi Tim,
I did similar changes as you did:
<configuration> <property> <name>yarn.nodemanager.aux-services</name> <value>mapreduce_shuffle</value> </property> <property> <name>yarn.nodemanager.env-whitelist</name> <value>JAVA_HOME,HADOOP_COMMON_HOME,HADOOP_HDFS_HOME,HADOOP_CONF_DIR,CLASSPATH_PREPEND_DISTCACHE,HADOOP_YARN_HOME,HADOOP_MAPRED_HOME</value> </property> <property> <name>yarn.nodemanager.local-dirs</name> <value>F:/big-data/data/tmp</value> </property> </configuration>And I cloud not start YARN nodemanager service because of the following error:
This issue is recorded here:
I cannot resolve this problem without running the commands as Administrator.
Based on the JIRA links, these issues should have been fixed. However it may not work because my Windows account is not a local account or domain account.
I will find sometime to try directly using a local account (without Microsoft account) to see if it works.
It seems you didn't get any issue when changing the local tmp folder, is that correct?

Re: Install Hadoop 3.2.1 on Windows 10 Step by Step Guide
Hi Tim,
Have you checked YARN web portal to see if you can see the Spark application is submitted successfully? You should be able to find more details there too (assuming you are run Spark with master set as yarn).
I’m working today and will try to replicate what you did in my machine when I am off work.

Hello Praveen,
If you close the cygwin windows and reopen it and then type the following:
Does that still list all the values?
And also, I noticed you are using mysql as hive metastore, have you configured all the values correctly? If not, I would recommend using derby if you are just installing Hive for learning. derby is built in however it only supports on session concurrently.

Re: Install Hadoop 3.2.1 on Windows 10 Step by Step Guide
Hi Saad,
Refer to the Reference section on this page: Default Ports Used by Hadoop Services (HDFS, MapReduce, YARN). It has the links to the official documentation about all the parameters you can configure in HDFS and YARN. It also shows the default values for each configurations.
For different versions of Hadoop, the default values might be different.

Hi,

http://localhost:9864/datanode.html
these 2 links were not opening once i reached till end, then i started changing values in hdfs-site.xml
to some other paths locations in E drive and then i think got lost.
Today when i run start-dfs.cmd then data and name node start without any error and i can see above 2 urls without any error.
Thanks for quick reply.
Can you also guide me where can i find and change ports values like 8088,9870 etc.
Thanks again for this tutorial.

Re: Install Hadoop 3.2.1 on Windows 10 Step by Step Guide
Hi Saad,
I don't see any error message in the log you pasted.
Can you please be more specific about the errors you encounterred.
For formatting namenode, it is correct to expect the namenode daemon to shutdown after the format is done. We will start all the HDFS and YAN daemons at the end.

Re: Apache Hive 3.1.1 Installation on Windows 10 using Windows Subsystem for Linux
This article is for Hive 3.1.1 installation on Windows 10 using WSL. All the command line needs to run in WSL bash window (not Command Prompt).
Based on your screenshot, you are trying to install it on Windows 10 directly. If that's the case, please following the following article:

Hey Raymond,
Thanks a lot brother for your prompt response.
This worked like a charm after amending mapred-site.xml with %HADOOP_HOME%. I made a mistake using the unix convention of the variable and was trying the same thing with $HADOOP_HOME$.
Successfully inserted data. Cheers!
