      Description

      From Lars George list up on hbase-dev:

      Hi,
      
      I went through the config values as per the defaults XML file (still
      going through it again now based on what is actually in the code, i.e.
      those not in defaults). Here is what I found:
      
      hbase.master.balancer.period - Only used in hbase-default.xml?
      
      hbase.regions.percheckin, hbase.regions.slop - Some tests still have
      it but not used anywhere else
      
      zookeeper.pause, zookeeper.retries - Never used? Only in hbase-defaults.xml
      
      
      And then there are differences between hardcoded and XML based defaults:
      
      hbase.client.pause - XML: 1000, hardcoded: 2000 (HBaseClient) and 30 *
      1000 (HBaseAdmin)
      
      hbase.client.retries.number - XML: 10, hardcoded 5 (HBaseAdmin) and 2 (HMaster)
      
      hbase.hstore.blockingStoreFiles - XML: 7, hardcoded: -1
      
      hbase.hstore.compactionThreshold - XML: 3, hardcoded: 2
      
      hbase.regionserver.global.memstore.lowerLimit - XML: 0.35, hardcoded: 0.25
      
      hbase.regionserver.handler.count - XML: 25, hardcoded: 10
      
      hbase.regionserver.msginterval - XML: 3000, hardcoded: 1000
      
      hbase.rest.port - XML: 8080, hardcoded: 9090
      
      hfile.block.cache.size - XML: 0.2, hardcoded: 0.0
      
      
      Finally, some keys are already in HConstants, some are in local
      classes and others used as literals. There is an issue open to fix
      this though. Just saying.
      
      Thoughts?
