Hi Hive Users, I am using Hive 2.3.3.
According to docs (https://cwiki.apache.org/confluence/display/Hive/Locking), they are ephemeral. But in the Zookeeper and Hive source Code, they seemed to be non-ephemeral. I ran the following query in Hive. *lock table discovery.defaultns* When I see the lock in zookeeper, it doesn't look like ephemeral node. [zk: localhost:2181(CONNECTED) 55] get /hive_zookeeper_namespace/discovery/defaultns/LOCK-EXCLUSIVE-0000000000 hive_20181112191555_d6640955-2806-4fa7-9e52-30d04c377a04:1542030355565:EXPLICIT:lock table discovery.defaultns exclusive:10.33.222.139 cZxid = 0x2400296808 ctime = Mon Nov 12 19:15:55 IST 2018 mZxid = 0x2400296808 mtime = Mon Nov 12 19:15:55 IST 2018 pZxid = 0x2400296808 cversion = 0 dataVersion = 0 aclVersion = 0 *ephemeralOwner = 0x0* dataLength = 134 numChildren = 0 Also in the code - https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/lockmgr/HiveTxnManagerImpl.java, the lock is KeepAlive/PERSISTENT and not EPHIMERAL . * HiveLock lck = lockMgr.lock(new HiveLockObject(tbl, lockData), mode, true);* Is it a bug or am I missing something? Thanks! -- Regards, Rajesh KSV
