Phabricator commented on HBASE-5407: ------------------------------------ Kannan has commented on the revision "[jira][HBASE-5407][89-fb] Show the per-region level request/sec count in the web ui". INLINE COMMENTS src/main/java/org/apache/hadoop/hbase/HServerLoad.java:279 I think these fields need not/shouldn't be part of the serialize/deserialize -- otherwise, we'll break client-server interop for the getClusterStatus call. We temporarily ran into similar problem before and the relevant stack is: at java.io.DataInputStream.readFully(DataInputStream.java:152) at org.apache.hadoop.hbase.HServerLoad$RegionLoad.readFields(HServerLoad.java:211) at org.apache.hadoop.hbase.HServerLoad.readFields(HServerLoad.java:512) at org.apache.hadoop.hbase.HServerInfo.readFields(HServerInfo.java:228) at org.apache.hadoop.hbase.ClusterStatus.readFields(ClusterStatus.java:226) at org.apache.hadoop.hbase.io.HbaseObjectWritable.readObject(HbaseObjectWritable.java:489) at org.apache.hadoop.hbase.io.HbaseObjectWritable.readFields(HbaseObjectWritable.java:230) at org.apache.hadoop.hbase.ipc.HBaseClient$Connection.receiveResponse(HBaseClient.java:534) at org.apache.hadoop.hbase.ipc.HBaseClient$Connection.run(HBaseClient.java:459) java.lang.reflect.UndeclaredThrowableException at $Proxy0.getClusterStatus(Unknown Source) at org.apache.hadoop.hbase.client.HBaseAdmin.getClusterStatus(HBaseAdmin.java:1076) We should remove these from serialize/deserialize, but the metrics should still be available for viewing the web-ui.
