Summary: MSCK repair table hang while running with multi threading
enabled
Key: HIVE-14925
URL: https://issues.apache.org/jira/browse/HIVE-14925
Project: Hive
Issue Type: Bug
Components: CLI
Affects Versions: 2.2.0
Reporter: Ratheesh Kamoor
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.
