Subject [jira] Created: (HIVE-1893) ConditionalResolverSkewJoin.getTasks may throw NullPointerException
Date Thu, 06 Jan 2011 02:27:47 GMT
ConditionalResolverSkewJoin.getTasks may throw NullPointerException

                 Key: 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.
