Robert Joseph Evans commented on YARN-690: ------------------------------------------ Vinod, Yes creating and resolving a JIRA in 2 hours is not ideal, but this is a Blocker that consisted on only a handful of lines of change, also the bylaws explicitly state that a waiting period is not needed for this vote because committers can retroactively -1 and pull the change out.

An UnknownHostException takes down > the RM... -- This message is automatically generated by JIRA.
