> 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:
