Subject [jira] [Created] (HIVE-2800) NPE in "create index" without comment clause in external metastore
Date Sat, 11 Feb 2012 01:18:59 GMT
NPE in "create index" without comment clause in external metastore
------------------------------------------------------------------

                 Key: HIVE-2800
                 URL: https://issues.apache.org/jira/browse/HIVE-2800
             Project: Hive
          Issue Type: Bug
          Components: Metastore
    Affects Versions: 0.8.1, 0.9.0
            Reporter: Daniel Dai
            Priority: Minor


This happens only when using external metastore (with --hiveconf hive.metastore.uris=thrift://localhost:8088
--hiveconf hive.metastore.local=false). Also if I gave a comment in the statement, this exception
go away.

Here is the statement:
create index test111 on table hcat_test(name) as 'compact' with deferred rebuild;

Here is the stack:
