Prakash Khemani updated HBASE-5618: ----------------------------------- Attachment: 0001-HBASE-5618-SplitLogManager-prevent-unnecessary-attem.patch > SplitLogManager - prevent unnecessary attempts to resubmits > ----------------------------------------------------------- > > Key: HBASE-5618 > URL: https://issues.apache.org/jira/browse/HBASE-5618 > Project: HBase > Issue Type: Improvement > Components: wal, zookeeper > Reporter: Prakash Khemani > Assignee: Prakash Khemani > Attachments: > 0001-HBASE-5618-SplitLogManager-prevent-unnecessary-attem.patch, > 0001-HBASE-5618-SplitLogManager-prevent-unnecessary-attem.patch > > > Currently once a watch fires that the task node has been updated (hearbeated) > by the worker, the splitlogmanager still quite some time before it updates > the "last heard from" time. This is because the manager currently schedules > another getDataSetWatch() and only after that finishes will it update the > task's "last heard from" time. > This leads to a large number of zk-BadVersion warnings when resubmission is > continuously attempted and it fails. > Two changes should be made > (1) On a resubmission failure because of BadVersion the task's lastUpdate > time should get upped. > (2) The task's lastUpdate time should get upped as soon as the > nodeDataChanged() watch fires and without waiting for getDataSetWatch() to > complete. -- This message is automatically generated by JIRA.
