Madhan Neethiraj commented on RANGER-769:
-----------------------------------------
[~aneela] Replacing http-*.jar(s) under hbase/lib with newer versions can cause
errors in HBase. The goal of RANGER-586 was to avoid adding libraries to
component classpath - due to potential impact to the component functionality.
Instead, the libraries that are needed by Ranger plugins should be placed in
ranger-<type>-plugin-impl directory; the plugin will load the contents of this
directory dynamically at runtime - only in the context of the authorization
calls from the component.
Inline with this approach, the necessary http-* libraries should simply be
added to ranger-hbase-plugin-impl folder. There should be no changes needed to
the libraries in hbase/lib directory. Please let me know if I can help with
further details.

> When we install HBase plugin, httpcore is not supplied to HBase lib folder.
> And HBase uses httpcore.4.1.3 version which is not compatible with
> hhtpclient.4.2.5 that causes following exception:
