[jira] [Commented] (HIVE-12160) Hbase table query execution fails in secured cluster when hive.exec.mode.local.auto is set to true

["Chaoyu Tang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-12160?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14984685#comment-14984685 ] 

Chaoyu Tang commented on HIVE-12160:
------------------------------------

[~aihuaxu] I know little about the security, and wonder if the child process can use any HBase delegation token instead of logging in using the keytab? 
[~prasadm], [~thejas] Could you help to review this patch? Thanks

> In a secured cluster with kerberos, a simple query like {{select count(*) from hbase_table;}} will fail with the following exception when hive.exec.mode.local.auto is set to true.
> {noformat}
> Error: Error while processing statement: FAILED: Execution Error, return code 134 from org.apache.hadoop.hive.ql.exec.mr.MapRedTask (state=08S01,code=134)
> {noformat}
> There is another scenario which may be caused by the same reason.
> Set hive.auto.convert.join to true, the join query {{select * from hbase_t1 join hbase_t2 on hbase_t1.id = hbase_t2.id;}} also fails with the following exception:
> {noformat}
> Error while processing statement: FAILED: Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.mr.MapredLocalTask (state=08S01,code=2)
> {noformat}
