Subject [jira] [Updated] (HDFS-3373) FileContext HDFS implementation can leak socket caches
Date Tue, 28 Aug 2012 17:54:08 GMT

John George updated HDFS-3373:

    Attachment: HDFS-3373.trunk.patch.1

TestConnCache failure is related to this JIRA. I had moved testDisableCache() from that test
to another test file because now it is not possible to change cache config per DFS. 

TestHftpDelegationToken is unrelated to this patch and has been failing in other builds as

> As noted by Nicholas in HDFS-3359, FileContext doesn't have a close() method, and thus
never calls DFSClient.close(). This means that, until finalizers run, DFSClient will hold
on to its SocketCache object and potentially have a lot of outstanding sockets/fds held on
