Did you follow step 3?

Step 3 - Install Hadoop native IO binary

If you've done that, you should be able to see the exe file in %HADOOP_HOME%/bin folder:

And also make sure HADOOP_HOME environment variable is configured correctly and also PATH environment variable has Hadoop bin folder.

You also need to restart PowerShell to source the latest environment variables if you are configure all these variables manually. 

Please let me know if that still exists.

Re: Use Google Cloud BigQuery as Data Source in Power BI

Yes, it's not working for me even though i deleted from third part apps. At least we can restrict the access. Thank you so much for your help..  

reply Reply

Hmm my understanding is that once you click Remove Access button that account will be gone when you next time try to connect to BigQuery from Power BI Desktop. At least that works for me. That one will only shows up there because you have not removed it from 'Apps with access to your account page': https://myaccount.google.com/permissions.

Better to raise this to Google support if it doesn't resolve the problem.

Re: Use Google Cloud BigQuery as Data Source in Power BI

Hi Raymond,

Thank you so much for your prompt reply, it helped me to remove access. We can change the password too..

But I am trying to remove account from that third party app. Unfortunately, there is no option to "Remove account" option. It still showing my account in that like this. It will be a great help if we find a way to remove account..


Thank you

Padma

Hi Chong,

I assume you followed all the exact steps?

And also is DFS services running successfully? You should be able to see two Command Prompt windows (one for name node and another for data node) if it is successful. The two windows will print live logs.

Use the following command, you should also able to see the listening port on 19000.

netstat -an  | grep 19000
  TCP    0.0.0.0:19000          0.0.0.0:0              LISTENING
  TCP    192.168.56.1:1427      192.168.56.1:19000     ESTABLISHED
  TCP    192.168.56.1:19000     192.168.56.1:1427      ESTABLISHED

You can also view the portal if it is started: http://localhost:9870.

If not that means the services are not started successfully.

I don't have my 3.0.0 environment in my system so hard to diagnose. However I do have the latest 3.2.1 environment and it is working properly:

Install Latest Hadoop 3.2.1 on Windows 10 Step by Step Guide

Maybe you can try this one and it will give better chance for me to find out any issue as I would have same environment as you.

Re: Install Hadoop 3.0.0 on Windows (Single Node)

Hi Raymond,

My core-site.xml has changed to 

<configuration>
    <property>
        <name>fs.defaultFS</name>
        <value>hdfs://localhost:19000</value>
    </property>
</configuration>
but the error still persist.
Please let me know if you need more information.
reply Reply

Hi Chong,

Can you show me your core-site.xml configuration file? 

My version works with the following settings however fs.default.name was deprecated in 3.0.0 and we'd better use fs.defaultFS.

<configuration>
   <property>
     <name>fs.default.name</name>
     <value>hdfs://0.0.0.0:19000</value>
   </property> </configuration>

Can you try change it to localhost?

<configuration>
    <property>
        <name>fs.defaultFS</name>
        <value>hdfs://localhost:19000</value>
    </property>
</configuration>

Re: Install Hadoop 3.0.0 on Windows (Single Node)

Hi Raymond,

Thanks for the blog! It is very useful!

I have an issue at the copy file to HDFS Issue. It stated that "your endpoint configuration is wrong".
May I know is there anyway that I can resolve this issue?


reply Reply

Hi Padma,

This is a good question. 

Once you authorize Power BI to access Big Query data, you can follow the steps below to remove it: 

  • Go to your Google Account.
  • On the left navigation panel, select Security.
  • On the Signing in to other sites panel, select Signing in with Google (https://myaccount.google.com/permissions). 
  • Select the site or app you want to remove. For this case, it's Power BI Desktop
  • Select Remove Access.

If you are trying to remove account access to BigQuery, you can use IAM feature in Google Cloud Console.


I hope that answers your question. Let me know if you have other questions.

I'm glad it worked. I also updated the page to reflect the JDK requirement.

BTW, if you want to build a native Hadoop 3.2.1 on Windows, you can follow this guide:

Re: Latest Hadoop 3.2.1 Installation on Windows 10 Step by Step Guide

Hello Raymond,

you nailed it! Everything works fine now (except, I feel somewhat stupid, for I knew about JDK8, but for some reason assumed this to be but a minimum requirement. It didn't occur to me to revert to the older version. Let's hope, this will save someone at least something.)

Thanks a lot!

Cheers,
Matthias

Hi Matthias,

As far as I know, JDK 13.0.1 is not supported. 

Please use JDK 1.8.x, it will work.

Even JDK 11 support is still in progress.

Re: Latest Hadoop 3.2.1 Installation on Windows 10 Step by Step Guide

Hi Raymond!

First of all: many thanks – a great how-to saving me hours!  Well, almost, that is.

I tried to install Hadoop 3.2.1 using your article. Everything went like a charm, I did encounter the problem mentioned when formatting the HDFS, the workaround worked fine.

However, when I reached Step 10 (launch YARN), both command windows run into a runtime exception. (See below)

The OS is a Windows 10 Edu N (english) and is up to date (as of today, Jan 25). The JDK is 13.0.1.

Any hint would be very much appreciated, as I'm far from being able to make sense of the messages!

Cheers from Vienna/Austria
Matthew
