Subject [jira] Commented: (HADOOP-5679) Resolve findbugs warnings in core/streaming/pipes/examples
Date Thu, 14 May 2009 07:24:45 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5679?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12709295#action_12709295

Jordà Polo commented on HADOOP-5679:

Running local jobs seems to fail for me since this patch was applied ("Mkdirs failed to create...").

The new code checks if either mkdirs() on hadoop.tmp.dir failed OR if it isn't a directory...
but it doesn't take into account that the directory may already exist. If the directory existed
before, it will always fail and exit since mkdirs() only returns "true" if it is able to create
the directory.

Wouldn't an AND be more appropriate here? I mean {{(!b && !tmpDir.isDirectory())}}
instead of {{(!b || !tmpDir.isDirectory())}} in src/core/org/apache/hadoop/util/RunJar.java,
line 111.
