------------------------------
Summary: Perform more effective sorting for RPC Handler Tasks
Key: HBASE-17065
URL: https://issues.apache.org/jira/browse/HBASE-17065
Project: HBase
Issue Type: Improvement
Reporter: Ted Yu
Priority: Minor
Under the 'Show All RPC Handler Tasks' tab, the tasks are not sorted according
to the duration they have been in the current state (see picture).
In TaskMonitorTmpl.jamon :
{code}
long now = System.currentTimeMillis();
Collections.reverse(tasks);
{code}
The underlying tasks are backed by CircularFifoBuffer, leading to ineffective
sorting.
We should display tasks with the longest duration (in current state) first.
