Hitesh Shah updated HBASE-5325:
-------------------------------
Attachment: HBASE-5325.wip.patch
Attached is a preliminary patch which adds a new hbasemasterinfo bean. Please
let me know your comments/thoughts on whether this is the right
approach/direction.
If it looks good, I can add something similar for the region server ( and
tests, etc ).
Using a hacked patch to display the /jmx output, this is what the information
would look like:
{quote}
{
"name" : "Hadoop:service=HBase,name=HBaseMasterInfo",
"modelerType" :
"org.apache.hadoop.hbase.master.HMasterCommandLine$LocalHMaster",
"ClusterId" : "d24914d7-75d3-4dcc-9e6f-0d7770833993",
"ZookeeperQuorumInfo" : "localhost:2181",
"CoprocessorsInfo" : "[]",
"MasterStartTime" : 1328223257723,
"MasterActiveTime" : 1328223257725,
"RegionServers" :
"{\"10.10.10.128:57366\":{\"requestsPerSecond\":0,\"startcode\":1328223257711,\"maxHeapMB\":987,\"numberOfOnlineRegions\":2,\"usedHeapMB\":34}}",
"DeadRegionServers" : "[]",
"RegionsInTransition" : "{}"
}

> Expose basic information about the master-status through jmx beans
