stack commented on HBASE-728:
-----------------------------

J-D: 

hbase can't fall too far behind hadoop releases.  We need to always have an 
offering for current hadoops.  If 0.2.0 hbase works on both 0.17 and 0.18 
hadoop -- we need to test a little more to be sure -- then we can leapfrog 
0.3.0 hbase back on to the hadoop TRUNK.  More work on 0.2.0 I'm afraid will 
just have us falling further behind.  Also, will exploiting the append 
additions to hadoop 0.18 in hbase 0.2.0 make it so it we're not API compatible 
with hadoop 0.17 (I may be wrong on the latter but I seem to recall rework of 
flush API).

Billy:

Though 0.17 hadoop seems to be slower than 0.16, IMO, we should have an hbase 
for all hadoop versions.
