Daniel Templeton commented on YARN-3742: ---------------------------------------- {quote}When creating RMFatalEvent, start the message with capital letters{quote} I did that on purpose because the {{RMFatalEvent}} will prepend the message with "RMFatalEvent of type %s, caused by %s". There were some cases where the message was logged in addition to being passed to the event constructor, and in those cases I started with a capital. {quote}Would "Critical thread, %s, exited unexpectedly" be a grammatically better message?{quote} Again, prepend "RMFatalEvent of type %s, caused by %s" => "RMFatalEvent of type %s, caused by a critical thread, %s, that exited unexpectedly". > YARN RM will shut down if ZKClient creation times out > ------------------------------------------------------- > > Key: YARN-3742 > URL: https://issues.apache.org/jira/browse/YARN-3742 > Project: Hadoop YARN > Issue Type: Bug > Components: resourcemanager > Affects Versions: 2.7.0 > Reporter: Wilfred Spiegelenburg > Assignee: Daniel Templeton > Attachments: YARN-3742.001.patch, YARN-3742.002.patch > > > The RM goes down showing the following stacktrace if the ZK client connection > fails to be created.
