    [ https://issues.apache.org/jira/browse/HBASE-15311?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15158670#comment-15158670 ] 

Samir Ahmic commented on HBASE-15311:
-------------------------------------

We have issue on this line
{code}
48             if (bcs.length < 2) {
{code}
since bcs can be null. I will fix this and submit patch.

> Currently we have this URL (rs-status?format=json&bcn=L1) for displaying block cache stats in json format. If arbitrary parameter is supplied instead of L1 it will cause NPE and we will display 500 error.
