Jason Lowe created HADOOP-9894: ---------------------------------- Summary: 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
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.
