Subject [jira] [Created] (HIVE-4906) IO Exception for empty file not found if IP address used in core site instead of hostname
Date Mon, 22 Jul 2013 10:58:50 GMT
Kanwaljit Singh created HIVE-4906:

             Summary: IO Exception for empty file not found if IP address used in core site
instead of hostname
                 Key: HIVE-4906
             Project: Hive
          Issue Type: Bug
          Components: HiveServer2
    Affects Versions: 0.10.0
            Reporter: Kanwaljit Singh

The hive server has core-site.xml with IP address for DFS namenode instead of the hostname.
But it also has host ip mapping. We are getting this error. I think the host reverse mapping
is not taking place while trying to access the folder on the HDFS.
