Konstantinos Karanasos commented on YARN-6059:
----------------------------------------------
Thanks for the latest patch, [~hrsharma]. Let's fix the following:
* In the {{RecoverPausedContainerLaunch}}, why is the
{{CONTAINER_EXITED_WITH_FAILURE}} message inside the finally statement? This
should not only be called only when the {{notInterrupted}} is true, but in all
cases. Let's put it just outside (after) the finally statement, like we do in
the {{RecoveredContainerLaunch}}. Also, you need to set the retCode to be the
output of the exec.signalContainer method.
* The failing test seems related to your changes:
"TestNMLeveldbStateStoreService.testContainerStorage:290 expected:<LAUNCHED>
but was:<PAUSED>".
* You can find the checkstyle issues by clicking on the corresponding link in
the report. You will see a few of them, which need to be fixed (the only one I
would not worry about is regarding the number of parameters). Let me know if
any of them is not self-explanatory. Pasting here too:
https://builds.apache.org/job/PreCommit-YARN-Build/14990/artifact/patchprocess/diff-checkstyle-hadoop-yarn-project_hadoop-yarn_hadoop-yarn-server_hadoop-yarn-server-nodemanager.txt.
Also address the warning shown in the output of the javadoc result.
Re: the ifs in the {{NMLeveldbStateStoreService}}: when a new recovery state is
stored for a container, a new entry is added to the StateStore. Then we iterate
over all of them. The ifs that you added essentially check the previous entry
found. So the code you added means that you are allowed to get a PAUSED
recovery container status immediately after a LAUNCHED, QUEUED or REQUESTED
status. If all these "transitions" are possible, then your code is correct.
