>             Project: Hive
>          Issue Type: Bug

> HiveMetaStoreChecker throws NullPointerException when doing a MSCK REPAIR TABLE.
> The bug is here:
> {code}
> ...
> 18      package org.apache.hadoop.hive.ql.metadata;
> ...
> 58      public class HiveMetaStoreChecker {
> ...
> 408        if (!directoryFound) {
> 409         allDirs.put(path, null);
> 410        }
> ...
> {code}
> allDirs is a ConcurrentHashMap and those does not allow either key or value to be null.
> I found the bug while trying to port https://github.com/klarna/HiveRunner to Hive 2.1.0
> Implemented explicit test case that exposes the bug here: 
> https://github.com/klarna/HiveRunner/blob/hive-2.1.0-NPE-at-msck-repair/src/test/java/com/klarna/hiverunner/MSCKRepairNPE.java
> Reproduce by cloning branch https://github.com/klarna/HiveRunner/tree/hive-2.1.0-NPE-at-msck-repair
> and run 
> {code} mvn -Dtest=MSCKRepairNPE clean test{code}
> ( Does not work on windows :( )
> Looks like this email thread talks about the same issue:
