Karthik Kambatla commented on YARN-1027:
----------------------------------------
For manual testing, I applied the patches yarn-1027-7.patch, yarn-1193-1.patch
(update clusterTimeStamp on transitionToActive), and yarn-1068-1.patch (support
for admin commands). Testing steps:
# *Start the RM*. Verified it was in Standby mode - Log, webui check, netstat
for ports check. jmap histo showed 168465 objects with 19476960 bytes.
# *Transition to Active*. Verified it was in Active mode - Log, webui, NM
connected, netstat for ports check. jmap histo showed 253430 objects with
31171544 bytes.
# *Run MR pi job*. Job finished successfully. WebUI worked as expected. jmap
histo showed 288406 objects with 35726096 bytes.
# *Transition to Standby*. Verified it was in Standby mode. jmap histo showed
282392 objects with 33975600 bytes.
# Repeated steps 2, 3, 4 once more.
# *Stop the RM*. RM stopped as expected and the logs didn't show any untoward
exceptions etc.
