Lars George commented on HBASE-3272:
------------------------------------

This is a "dupe" to HBASE-2721. Closing it out as well.

> From Lars George list up on hbase-dev:
> {code}
> 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?
