Subject [jira] [Commented] (HIVE-11956) SHOW LOCKS should indicate what acquired the lock
Date Fri, 27 May 2016 23:40:12 GMT

    [ https://issues.apache.org/jira/browse/HIVE-11956?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15304993#comment-15304993
] 

Wei Zheng commented on HIVE-11956:
----------------------------------

1. You need to make changes to newFormatSchema in ShowLocksDesc as well for the additional
column added for show locks
2. For the modified methods in HiveEndPoint, there's "throws IOException" in comment header
which isn't thrown by the methods
3. In TestDbTxnManager2.testShowLocksAgentInfo(), do you mean txnMgr.acquireLocks(driver.getPlan(),
ctx, "XYZ");
4. Unused import org.apache.hadoop.hive.metastore.txn.TxnStore in TestStreaming.java
5. I guess you meant to use agentInfo in TestStreaming.testBucketing() and testFileDump()

> This can be a queryId, Flume agent id, Storm bolt id, etc.  This would dramatically help
diagnosing issues.
