> Project: Hive
> Issue Type: Bug
> Components: CLI
> Affects Versions: 2.2.0
> Reporter: Ratheesh Kamoor
> Assignee: Pengcheng Xiong
> Priority: Critical
>
> MSCK REPAIR TABLE hanging while running with multi-threading enabled
> (default). I think it is because of a major design flaw in how thread pool
> implemented in HiveMetaSoreChecker class / checkPartitionDirs method. This
> method has a thread pool which register Callable but callable makes a
> recursive call to checkPartitionDirs method again. This code will hang when
> number of directories is more than thread pool size.
