ASF GitHub Bot commented on FLINK-5480: --------------------------------------- Github user ShashwatRastogi-Reflektion commented on the issue: https://github.com/apache/flink/pull/3117 @zentol I am using flink 1.3.2. Normally, I don't use `--allowNonRestoredState` and I get an error while restarting the job. After using this `allowNonRestoredState` the job starts up fine but there is a data loss because of lost state, which is what I want to avoid. I think, the problem with my implementation is that I am wrongly assigning some ids to the operators. Is there sure-shot way of finding out uid or uid-hash generated by flink for each operator(with/without chaining) ? > User-provided hashes for operators > ---------------------------------- > > Key: FLINK-5480 > URL: https://issues.apache.org/jira/browse/FLINK-5480 > Project: Flink > Issue Type: Improvement > Components: DataStream API > Affects Versions: 1.2.0 > Reporter: Stefan Richter > Assignee: Stefan Richter > Priority: Major > Fix For: 1.2.0, 1.3.0 > > > We could allow users to provided (alternative) hashes for operators in a > StreamGraph. This can make migration between Flink versions easier, in case > the automatically produced hashes between versions are incompatible. For > example, users could just copy the old hashes from the web ui to their job. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
