Pull request overview

This PR updates Apache HBase dependencies from version 2.6.0 to 2.6.4 and migrates from standard HBase client libraries to their shaded counterparts. The shaded versions help avoid classpath conflicts by relocating transitive dependencies into a separate package namespace.

Changes:

• Updated HBase version from 2.6.0 to 2.6.4 across project configuration files
• Replaced hbase-client and hbase-server dependencies with hbase-shaded-client and hbase-shaded-mapreduce
• Updated import statement to use the shaded configuration class path
