Kuhu Shukla updated HDFS-12754:
-------------------------------
Attachment: HDFS-12754.002.patch
Thank you for the comments [~yangjiandan]. I do an additional remove call for
the LeaseRenewer in the case of socket time out, which makes it so that a later
get() call will return a new renewer instance for a dfsclient. Also the patch
adds your test for completeness.
