Subject [jira] Commented: (HADOOP-2344) Free up the buffers (input and error) while executing a shell command before waiting for it to finish.
Date Wed, 12 Dec 2007 07:01:43 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2344?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12550854
] 

Amar Kamat commented on HADOOP-2344:
------------------------------------

Changes made to the patch other than the javadoc changes
* logging some of the exceptions in {{ShellCommand}} and throwing the main/imp ones.
* closing the streams explicitly.
* ignoring the error of {{df -k}} since exit code provides the required error information

> Process.waitFor() should be invoked after freeing up the input and error stream.  While
fixing https://issues.apache.org/jira/browse/HADOOP-2231 we found that this might be a possible
cause.
