[jira] [Commented] (FLINK-9776) Interrupt TaskThread only while in User/Operator code

["Robert Metzger (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-9776?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16767026#comment-16767026 ] 

Robert Metzger commented on FLINK-9776:
---------------------------------------

This change has actually been merged to Flink 1.6.0 (as you can see from the commit) [https://github.com/apache/flink/commit/53e6657658bc750b78c32e91fa7e2c02e8c54e33]

The fixversion has probably been pushed forward because the ticket was still open.

I'm adjusting the fix version from 1.6.4 to 1.6.0

> Upon cancellation, the task thread is periodically interrupted.
> This helps to pull the thread out of blocking operations in the user code.
> Once the thread leaves the user code, the repeated interrupts may interfere with the shutdown cleanup logic, causing confusing exceptions.
> We should stop sending the periodic interrupts once the thread leaves the user code.
