Gopal V created HIVE-20854: ------------------------------ Summary: Sensible Defaults: Hive's Zookeeper heartbeat interval is 20 minutes, change to 2 Key: HIVE-20854 URL: https://issues.apache.org/jira/browse/HIVE-20854 Project: Hive Issue Type: Bug Reporter: Gopal V
{code} HIVE_ZOOKEEPER_SESSION_TIMEOUT("hive.zookeeper.session.timeout", "1200000ms", new TimeValidator(TimeUnit.MILLISECONDS), "ZooKeeper client's session timeout (in milliseconds). The client is disconnected, and as a result, all locks released, \n" + "if a heartbeat is not sent in the timeout."), {code} That's 1,200,000ms which is too long for all practical purposes - a 20 minute outage in case a node has a failure is too long. That is too long for the JDBC load-balancing, LLAP failure tolerance and the lock manager expiry. Change to 2 minutes, as a sensible default -- This message was sent by Atlassian JIRA (v7.6.3#76005)
