Are all those jars included in the current directory where you initiated the spark-shell?

You can manually put them into \jars directory in your Spark installation.

Re: Spark 3.0.1: Connect to HBase 2.4.1

I think there is no issue with the build. But I'm unable to connect to Hbase from Spark. I'm using a docker environment where Zookeeper, HDFS, Spark, and HBase run in different containers in the same network.

Here are the jars I'm using.

spark-shell --jars hbase-spark-protocol-shaded-,htrace-core4-4.2.0-incubating.jar,hbase-shaded-protobuf-3.5.1.jar,protobuf-java-2.5.0.jar,hbase-protocol-2.4.8.jar,hbase-shaded-miscellaneous-3.5.1.jar,hbase-mapreduce-2.4.8.jar,hbase-server-2.4.8.jar,hbase-client-2.4.8.jar,hbase-common-2.4.8.jar,hbase-spark-1.0.1-SNAPSHOT.jar,hadoop-common-2.8.5.jar --files hbase-site.xml

I have almost all the required jars but still seeing below error. I tried my best to debug the isue but didn't find a way to get rid of this. Please advise me how to resolve this or redirect me if there is any detailed documentation about prerequisites.
