Solr Admin Handler error

Below is the warning written to the system log file in DSE, when we solr admin handler class in solrconfig.xml like from previous 6.x versions.

WARN [SecondaryIndexManagement:6] 2016-04-03 17:15:11,423 AdminHandlers.java:103 - <requestHandler name="/admin/"

class="solr.admin.AdminHandlers" /> is deprecated . It is not required anymore

Cause: 

This is an issue because in Solr 6.x solr.admin.AdminHandlers has been removed. ( SOLR-7388) 

In solrconfig.xml

Remove the below line.

<requestHandler class="solr.admin.AdminHandlers" name="/admin/"/>

Then restart all DSE service on all nodes.
