> Key: FLINK-27070
> URL: https://issues.apache.org/jira/browse/FLINK-27070
> Project: Flink
> Issue Type: Sub-task
> Components: Table Store
> Affects Versions: table-store-0.1.0
> Reporter: Caizhi Weng
> Assignee: Caizhi Weng
> Priority: Major
> Labels: pull-request-available
> Fix For: table-store-0.1.0
>
>
> When testing table store I'm faced with the following warning messages:
> {code}
> org.apache.org.impl.MemoryManagerImpl [] - Owner thread expected
> Thread[Writer -> Local Committer (1/16)#0,5,Flink Task Threads], got
> Thread[pool-8-thread-1,5,Flink Task Threads]
> {code}
> This is because {{OrcBulkWriterFactory}} is not thread safe (it keeps
> {{WriterOptions}} as a class member and creates writers from the same
> {{WriterOptions}} object, which is not thread safe).
> What we should do is to reuse {{FileFormat}} instead of
> {{DecodingFormat}}/{{EncodingFormat}} to ensure thread safety.
