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 well.
Attaching a patch with testDisableCache() removed from TestConnCache to a new
file
> FileContext HDFS implementation can leak socket caches
> ------------------------------------------------------
>
> Key: HDFS-3373
> URL: https://issues.apache.org/jira/browse/HDFS-3373
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs client
> Affects Versions: 2.0.0-alpha, 3.0.0
> Reporter: Todd Lipcon
> Assignee: John George
> Attachments: HDFS-3373.branch-23.patch, HDFS-3373.trunk.patch,
> HDFS-3373.trunk.patch.1
>
>
> 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 to.
