Subject [jira] [Commented] (HDFS-12754) Lease renewal can hit a deadlock
Date Thu, 02 Nov 2017 22:07:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12754?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16236680#comment-16236680

Kuhu Shukla commented on HDFS-12754:
------------------------------------

Adding the test as it is causes a hang since the deadlock of the surefire process for this
test class cannot recover or shutdown without external intervention. Thread joins or interrupts
do not work therefore. Will update on more finds or ways to fix the test but would appreciate
any more ideas from [~yangjiandan] / [~elgoiri]/ [~kihwal]. Thanks again.

> The Client and the renewer can hit a deadlock during close operation since closeFile()
reaches back to the DFSClient#removeFileBeingWritten. This is possible if the client class
close when the renewer is renewing a lease.
