Subject [jira] Commented: (HADOOP-2420) Use exit code to detect normal errors while excuting 'ls' in Local FS
Date Fri, 04 Jan 2008 01:09:34 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2420?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12555748#action_12555748

dhruba borthakur commented on HADOOP-2420:
------------------------------------------

+1 Code looks good. But why does serialversionUid need to be defined, this class is not being
serialized, is it?

> Local FileSystem runs {{ls -ld}} find file permissions, owner and group for a file. Currently
it parses message in the exception to check if the command returned an error due to expected
conditions like missing file. 
> HADOOP-2344 add interface to get error code returned by the external process. Local FS
should use that.
