ASF subversion and git services commented on KUDU-2612: ------------------------------------------------------- Commit 096f1ddf09047ea11d78a661010dd549ffa9af51 in kudu's branch refs/heads/master from Alexey Serbin [ https://gitbox.apache.org/repos/asf?p=kudu.git;h=096f1dd ] KUDU-2612: fix txn keepalive failover in Java client Prior to this patch, transaction keepalive heartbeater in Java client wouldn't switch to a different TxnManager instance fast enough when current TxnManager is no longer available (e.g., corresponding Kudu master stopped or shutdown). That might lead to unintended termination of a multi-row transaction if a leader master was shutdown while the transaction was in progress. The issue was due to: * using long timeout (i.e. the default one) for issuing KeepTransactionAlive RPCs * sending KeepTransactionAlive RPCs synchronously on the client's HashedWheelTimer timer which was supposed to run only short tasks This patch fixes the issue mentioned above and adds a new test scenario which verifies that Kudu Java client switches to a different TxnManager instance when the previously used one is no longer available.
