[jira] [Created] (HBASE-4281) Add facility to dump current state of
all executors
Add facility to dump current state of all executors
---------------------------------------------------
Key: HBASE-4281
URL: https://issues.apache.org/jira/browse/HBASE-4281
Project: HBase
Issue Type: New Feature
Components: master, regionserver, util
Affects Versions: 0.92.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Fix For: 0.92.0
For debugging, it's useful to be able to understand the current state of all of the executors. This is like the /stacks servlet, but with executor-specific information, including what's queued and not yet running.

-------------------------------
Attachment: 0006-HBASE-4281.-ExecutorService-monitoring-v2.patch
I'd used some 0.90 types in the previous patch. This one is trunk-safe. I'll try to run some tests on the whole trunk with the whole patch series before committing.

Jean-Daniel Cryans commented on HBASE-4281:
-------------------------------------------
+1
A trickle of javadoc on public methods missing them would be good if you want to do that on commit, along with fixing a few of those long lines.
