Subject [jira] [Commented] (HADOOP-10517) InputStream is not closed in two methods of JarFinder
Date Mon, 05 May 2014 04:59:15 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10517?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13989281#comment-13989281

Swarnim Kulkarni commented on HADOOP-10517:

It looks like there is a bug which we can fix with this JIRA. The closeEntry is called twice,
Once here[1] and second here[2]. So if the "if" portion gets executed, we try to close the
entry twice resulting in the error in the JUnit. I think we can remove the one inside "if"
to fix the issue.
