Subject [jira] [Updated] (HDFS-3754) BlockSender doesn't shutdown ReadaheadPool threads
Date Thu, 02 Aug 2012 17:30:03 GMT

     [ https://issues.apache.org/jira/browse/HDFS-3754?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Eli Collins updated HDFS-3754:
------------------------------

    Attachment: hdfs-3754.txt

Patch attached. I confirmed TestSeekBug no longer hangs (after using the workaround from HDFS-3753)
with this patch.

The same change applies to branch-1, verified {{ant clean test -Dtestcase=TestSeekBug -Dcompile.native=true}}
no longer hangs.

> The BlockSender doesn't shutdown the ReadaheadPool threads so when tests are run with
native libraries some tests fail (time out) because shutdown hangs waiting for the outstanding
threads to exit.
