Jingsong Lee reassigned FLINK-27652:
------------------------------------
Assignee: Jane Chan
> CompactManager.Rewriter cannot handle different partition keys invoked
> compaction
> ---------------------------------------------------------------------------------
>
> Key: FLINK-27652
> URL: https://issues.apache.org/jira/browse/FLINK-27652
> Project: Flink
> Issue Type: Bug
> Components: Table Store
> Affects Versions: table-store-0.2.0
> Reporter: Jane Chan
> Assignee: Jane Chan
> Priority: Major
> Fix For: table-store-0.2.0
>
>
> h3. Issue Description
> When enabling {{commit.force-compact}} for the partitioned managed table,
> there had a chance that the successive synchronized
> writes got failure. The current impl of {{CompactManager.Rewriter}} is an
> anonymous class in {{FileStoreWriteImpl}}. However, the {{partition}} and
> {{bucket}} are referenced as local variables, and the dataFileReader is
> initiliazed when rewrite is called; and this may lead to the {{rewrite}}
> method messing up with the wrong data file with the {{partition}} and
> {{bucket}}.
> h3. Root Cause
> {code:java}
> Caused by: java.io.IOException: java.util.concurrent.ExecutionException:
> java.lang.RuntimeException: java.io.FileNotFoundException: File
> file:/var/folders/xd/9dp1y4vd3h56kjkvdk426l500000gn/T/junit5920507275110651781/junit4163667468681653619/default_catalog.catalog/default_database.db/T1/f1=Autumn/bucket-0/data-59826283-c5d1-4344-96ae-2203d4e60a57-0
> does not exist or the user running Flink ('jane.cjm') has insufficient
> permissions to access it. at
> org.apache.flink.table.store.connector.sink.StoreSinkWriter.prepareCommit(StoreSinkWriter.java:172)
> {code}
> However, data-59826283-c5d1-4344-96ae-2203d4e60a57-0 does not belong to
> partition Autumn. It seems like the rewriter found the wrong partition/bucket
> with the wrong file.
