Possible class replacements

[jeongho장정호 <je...@nexr.com>]

Hi,

I'm new here :)

Currently, I'm trying to extend hbase for test without touching codes in
hbase and thinking class replacement with property is the best way to
extend it.
I know that there are many classes which can be replaced with custom
implementations such as HRegion.java by hbase.hregion.impl property.
But I couldn't find where all possible classes are listed.

So anybody, could you please guide me where I can find them?

Thanks,

I do not believe such a list exists.  You can specify alternate
HRegionServer class and possible Master.  HRegion too and then there
are a few places where you can influence policies such as when to
split and when to remove WAL logs.

You might also look to coprocessors if you are about customizing HBase.
