Subject [jira] [Commented] (HBASE-16450) Shell tool to dump replication queues
Date Fri, 19 Aug 2016 16:11:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16450?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15428372#comment-15428372

stack commented on HBASE-16450:
-------------------------------

Looks nice. You have a picture of what it looks like when you do the dump call?

What you think of the findbugs complaints [~esteban]?

These have to be static?

+  private static final Log LOG = LogFactory.getLog(DumpReplicationQueues.class.getName());
+
+  private static Configuration conf;
+
+  private static ReplicationAdmin replicationAdmin;
+  private static String replicationZNode;
+  private static ClusterConnection connection;
+  private static Path oldLogDir, logDir, rootDir;
+  private static FileSystem fs;


Put this in a finally block? 
+    zkw.close();

... doesn't matter much since jvm will be exiting...

The core of dumpQueuesOrFix could be moved to a new method where you pass in the loop item?


But no biggie.

Looks great. We need this kind of tooling bad. Thanks [~esteban]

> 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.
