-------------------------------------
Tested in CDH kerberized cluster with sentry.
[~ctang.ma], could you review the code?
> SMB MapJoin failed for Hive on Spark when kerberized

> Key: HIVE-14015
> URL: https://issues.apache.org/jira/browse/HIVE-14015
> Project: Hive
> Issue Type: Bug
> Components: Logical Optimizer
> Affects Versions: 1.1.0, 2.0.0
> Reporter: Yongzhi Chen
> Assignee: Yongzhi Chen
> Attachments: HIVE-14015.1.patch
>
>
> java.io.IOException:
> org.apache.hadoop.ipc.RemoteException(java.io.IOException): Delegation Token
> can be issued only with kerberos or web authentication
> It could be reproduced:
> 1) prepare sample data:
> a=1
> while [[ $a -lt 100 ]]; do echo $a ; let a=$a+1; done > data
> 2) prepare source hive table:
> CREATE TABLE `s`(`c` string);
> load data local inpath 'data' into table s;
> 3) prepare the bucketed table:
> set hive.enforce.bucketing=true;
> set hive.enforce.sorting=true;
> CREATE TABLE `t`(`c` string) CLUSTERED BY (c) SORTED BY (c) INTO 5 BUCKETS;
> insert into t select * from s;
> 4) reproduce this issue:
> SET hive.execution.engine=spark;
> SET hive.auto.convert.sortmerge.join = true;
> SET hive.auto.convert.sortmerge.join.bigtable.selection.policy =
> org.apache.hadoop.hive.ql.optimizer.LeftmostBigTableSelectorForAutoSMJ;
> SET hive.auto.convert.sortmerge.join.noconditionaltask = true;
> SET hive.optimize.bucketmapjoin = true;
> SET hive.optimize.bucketmapjoin.sortedmerge = true;
> select * from t join t t1 on t.c=t1.c;
