Lefty Leverenz commented on HIVE-12366: --------------------------------------- Doc note: This adds *hive.txn.heartbeat.threadpool.size* to HiveConf.java in 1.3.0 and 2.1.0 (and perhaps 2.0.0) so it needs to be documented in Configuration Properties and the Hive Transactions doc. * [Configuration Properties -- Transactions and Compactor | https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-TransactionsandCompactor] * [Hive Transactions -- Configuration | https://cwiki.apache.org/confluence/display/Hive/Hive+Transactions#HiveTransactions-Configuration] > Refactor Heartbeater logic for transaction > ------------------------------------------ > > Key: HIVE-12366 > URL: https://issues.apache.org/jira/browse/HIVE-12366 > Project: Hive > Issue Type: Bug > Components: Transactions > Reporter: Wei Zheng > Assignee: Wei Zheng > Labels: TODOC1.3 > Attachments: HIVE-12366.1.patch, HIVE-12366.11.patch, > HIVE-12366.12.patch, HIVE-12366.13.patch, HIVE-12366.14.patch, > HIVE-12366.15.patch, HIVE-12366.2.patch, HIVE-12366.3.patch, > HIVE-12366.4.patch, HIVE-12366.5.patch, HIVE-12366.6.patch, > HIVE-12366.7.patch, HIVE-12366.8.patch, HIVE-12366.9.patch, > HIVE-12366.branch-1.patch, HIVE-12366.branch-2.0.patch > > > Currently there is a gap between the time locks acquisition and the first > heartbeat being sent out. Normally the gap is negligible, but when it's big > it will cause query fail since the locks are timed out by the time the > heartbeat is sent. > Need to remove this gap. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
