ConditionalResolverSkewJoin.getTasks may throw NullPointerException
-------------------------------------------------------------------
Key: HIVE-1893
URL: https://issues.apache.org/jira/browse/HIVE-1893
Project: Hive
Issue Type: Bug
Components: Query Processor
Affects Versions: 0.6.0
Environment: RedHat 2.6.18-164.11.1.el5, JDK 1.6.0_06
Reporter: Zhai Yantang
Fix For: 0.6.0
In ConditionalResolverSkewJoin.getTasks(HiveConf, Object), FileStatus[] fstatus
= inpFs.listStatus(dirPath) and then fstatus.length is accessed. However,
DistributedFileSystem.listStatus(Path p) could return null, thus fstatus may be
null, and then fstatus.length will throw NullPointerException.
