[jira] [Updated] (HBASE-16450) Shell tool to dump replication
queues
[ https://issues.apache.org/jira/browse/HBASE-16450?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sean Busbey updated HBASE-16450:
--------------------------------
Release Note:
New tool to dump existing replication peers, configurations and queues when using HBase Replication.
hbase org.apache.hadoop.hbase.replication.regionserver.DumpReplicationQueues
The tool provides two flags:
--distributed This flag will poll each RS for information about the replication queues being processed on this RS.
By default this is not enabled and the information about the replication queues and configuration will be obtained from ZooKeeper.
--hdfs When --distributed is used, this flag will attempt to calculate the total size of the WAL files used by the replication queues. Since its possible that multiple peers can be configured this value can be overestimated.

> Currently there is no way to dump list of the configured queues and the replication queues when replication is enabled. Unfortunately the HBase master only offers an option to dump the whole content of the znodes but not details on the queues being processed on each RS.
