Arpit Agarwal updated HADOOP-9894: ---------------------------------- Attachment: hadoop-9894.01.patch Thanks for posting the detailed analysis Jason. Here is an attempt at fixing it. > Race condition in Shell leads to logged error stream handling exceptions > ------------------------------------------------------------------------ > > Key: HADOOP-9894 > URL: https://issues.apache.org/jira/browse/HADOOP-9894 > Project: Hadoop Common > Issue Type: Bug > Components: util > Affects Versions: 2.1.0-beta > Reporter: Jason Lowe > Attachments: hadoop-9894.01.patch > > > Shell.runCommand starts an error stream handling thread and normally joins > with it before closing the error stream. However if parseExecResult throws > an exception (e.g.: like Stat.parseExecResult does for FileNotFoundException) > then the error thread is not joined and the error stream can be closed before > the error stream handling thread is finished. This causes the error stream > handling thread to log an exception backtrace for a "normal" situation. -- This message is automatically generated by JIRA.
