Hudson commented on MAPREDUCE-4570: ----------------------------------- Integrated in Hadoop-Common-trunk-Commit #2613 (See [https://builds.apache.org/job/Hadoop-Common-trunk-Commit/2613/]) MAPREDUCE-4570. ProcfsBasedProcessTree#constructProcessInfo() prints a warning if procfsDir/<pid>/stat is not found.

What is happening here is that > the list of all processes in the system is found, and then later the > procfsDir/<pid>/stat file for each is opened. This warning is thrown when the > process finishes before the stat file is opened, and hence the file is no > longer there. This could normally happen, and shouldn't signify a waring. An > info message is sufficient. I'll be uploading a patch momentarily. -- This message is automatically generated by JIRA.
