Hadoop (HBase) Connectivity Issues

Hi
I am working on Hadoop integration. As part of this exercise, I have created a Data-Admin-Hadoop record and configured the parameters for HDFS and HBase connections. I have imported all the required Jars mentioned in the PDN Article (https://pdn.pega.com/jar-file-dependencies-hbase-and-hdfs-data-sets#com…).
commons-configuration-1.6.jar
hadoop-auth-2.4.1.jar
hadoop-common-2.4.1.jar
hbase-client-0.98.3-hadoop2.jar
hbase-common-0.98.3-hadoop2.jar
hbase-protocol-0.98.3-hadoop2.jar
htrace-core-2.04.jar
protobuf-java-2.5.0.jar
zookeeper-3.4.5.jar
commons-io-2.4.jar
hadoop-hdfs-2.4.1.jar
protobuf-java-2.5.0.jar
parquet-hadoop-1.8.1.jar
parquet-common-1.8.1.jar
parquet-column-1.8.1.jar
parquet-format-2.3.1.jar
parquet-encoding-1.8.1.jar
htrace-core4.jar
hadoop-auth-2.6.0-cdh5.8.0.jar
hadoop-common-2.6.0-cdh5.8.0.jar
hadoop-hdfs-2.6.0-cdh5.8.0.jar
I am able to successfully do the test connectivity for HDFS. But HBase configuration had issues with connectivity - when I do test connectivity, got the following message even though I had imported all the required Jars.
"Connection cannot be established. Please check your configuration. Missing HBase Java client classes on the classpath (are jars uploaded into container?)"
Are there any additional Jars that I need to deploy for Pega 7.3?
I am using Pega Personal Edition - 7.3 and Hadoop Cloudera VM distribution.
Need your help to resolve the issues.

Steps to Reproduce
1. Need Hadoop Cloudera Distribution in Oracle VM Version
2. Deploy the required Jars in Pega Personal Edition v7.3
3. Create Data-Admin-Hadoop record and enter required configuration in it for Both HDFS & HBase.
4. Do the test connectivity.

Error Message

Connection cannot be established. Please check your configuration. Missing HBase Java client classes on the classpath (are jars uploaded into container?)

Attempted Solutions

Tried to import additional jars as described in the comments section of the PDN article but it didn't work.
