Manikandan R commented on YARN-3839:
------------------------------------
{quote}I don't believe we should remove the NMNotYetReadyException from the
ServeryProxy exception map. Otherwise if a newer client talks to an older
server that is still throwing the old exception then the new client will not
handle it gracefully.{quote}
Ok. Taken care. Attached new patch.
{quote}Please look a bit deeper into the test failures, there may be races that
are not going well once the check for the blocked boolean was removed and now
we're proceeding quicker than we would have before.{quote}
I spent some time on these failures, but don't see any issues. For example,
{code}java.lang.Exception: test timed out after 120000 milliseconds{code}
failures in
TestContainerManagerSecurity.testContainerManager:158->testNMTokens:253->testStartContainer:478->startContainer:557
is reproducible even in my local working copy and can be avoided by increasing
timeout value for specific test case. However, am getting NPE in line
containing {code}nmContet.getContainers().get(containerId){code} in
{code}waitForContainerToFinishOnNM(){code} method in
TestContainerManagerSecurity.java, but don't think it is related to this patch.
Please let me know your thoughts.
