Subject [jira] [Commented] (HBASE-15599) Loading Master/table.jsp creates/destroys ZK connection
Date Thu, 07 Apr 2016 10:03:25 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15599?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15230031#comment-15230031

Samir Ahmic commented on HBASE-15599:
-------------------------------------

[~ndimiduk] i have notice same behavior on master branch. After some digging i have found
that connection to zookeeper is created by 
{code}
CompactionState compactionState = admin.getCompactionState(table.getName());
{code} 
 in table.jsp. 
We are always creating zookeeper connection in  admin#getCompactionState() in order to check
compaction state of 'hbase:meta' table. We can change this to create zk connection only in
case when we are checking 'hbase:meta table'.

I will create new ticket to add this change to admin#getCompactionState() for master branch.

> Noticed while tailing master log and browsing master WebUI: refreshing table.jsp results
in ZK connection logged. JSP should probably be reusing existing connection.
