[jira] [Commented] (FLINK-8042) Retry individual failover-strategy
for some time first before reverting to full job restart
[ https://issues.apache.org/jira/browse/FLINK-8042?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16354124#comment-16354124 ]
Monal Daxini commented on FLINK-8042:
-------------------------------------
This bug is quite detrimental to workloads where there is large state and is massively parallel. This is potential blocker for one of our use cases. Causing a full job restart takes while to recover.
With local state recovery (potentially targeted for 1.5) and running the job with 1 or 2 extra TaskManagers might mitigate this to an extent. However, does not solve the problem.
It would be good to address this sooner than later. Do we have a design doc that outlines the interface changes, if not can we please start one.

> Let's we will a taskmanager node. When Flink tries to attempt fine grained recovery and fails replacement taskmanager node didn't come back in time, it reverts to full job restart.
> Stephan and Till was suggesting that Flink can/should retry fine grained recovery for some time before giving up and reverting full job restart
