> This patch is the parts of the HBASE-2001 patch which implements support for the RegionObserver
interface. This enables extension of the regionserver through stacking dynamically loaded
classes i.e. from jars on HDFS onto upcalls from HRegion. I made some improvements over the
other patch and added a test case. There are other parts of 2001 which need some thought and
some work and would not be useful without client side support. This is the part which could
be immediately useful.
