> Currently. Flink Inline cluster and compact distribute strategy are
> rebalanced. when a compact operation doesn't succeed then it rolls back and
> executes again later. rebalance strategy may lead to the same file send to a
> different thread so accessed by multiple threads. such as failed rollback
> thread and normal compact thread. cause follow error:
> {code:java}
> writing record HoodieRecord{key=HoodieKey
> { recordKey=a:100 partitionPath=2022-06-30/18}
> , currentLocation='null', newLocation='null'}
> java.io.IOException: The file being written is in an invalid state. Probably
> caused by an error thrown previously. Current state: COLUMN
