-----------------------------------
Hi Stack.
This patch is to add total read/write request number and read/write request per second for each region in 89-fb branch.
For the apache trunk, I will also need to add the read/write request per second only.

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)

We should remove these from serialize/deserialize, but the metrics should still be available for viewing the web-ui.

src/main/java/org/apache/hadoop/hbase/metrics/RequestMetrics.java:53 In the run function of the HRegion server will periodically (hbase.regionserver.msginterval) call createRegionLoad, which will refresh the request/sec metrics. It follows the same way how other metrics get updated.
Also when you refresh the web page, this function will be called as well.
src/main/resources/hbase-webapps/regionserver/regionserver.jsp:22 sure. I will remove them.

BTW, does the writeRequestsCount mean the write request/sec ? Or this is an aggregated number ?

Mikhail Bautin resolved HBASE-5407.
-----------------------------------
Resolution: Fixed
Liyin: it looks like the 89-fb patch has been committed internally. As this is an 89-fb-only JIRA, resolving the issue so that we can sync internal 89-fb changes into the externally visible branch.

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.
