Eugene Koifman commented on HIVE-7483:
--------------------------------------
DbTxnManager will use DbLockManager(), so I think hive.zookeeper.quorum is not
relevant.
> hive insert overwrite table select from self dead lock

> Reporter: Xiaoyu Wang
>
> CREATE TABLE test(
> id int,
> msg string)
> PARTITIONED BY (
> continent string,
> country string)
> CLUSTERED BY (id)
> INTO 10 BUCKETS
> STORED AS ORC;
> alter table test add partition(continent='Asia',country='India');
> in hive-site.xml:
> hive.txn.manager=org.apache.hadoop.hive.ql.lockmgr.DbTxnManager;
> hive.support.concurrency=true;
> hive.zookeeper.quorum=zk1,zk2,zk3;
> in hive shell:
> set hive.input.format=org.apache.hadoop.hive.ql.io.HiveInputFormat;
> insert into test table some records first.
> then execute sql:
> insert overwrite table test partition(continent='Asia',country='India')
> select id,msg from test;
