Another query ..

hadoop 0.21.0 has been released with the stable hdfs append feature..

Should we do anything in hbase(modify / apply some patch) to use this hdfs
append feature or hbase takes care of this in-built?? 

from web i've seen that this append feature(hdfs-265) is different from what
hbase expects(hdfs-200).. 

can anyone pls explain what is the background???

Is there a master running?  If so, what does it say in the master logs?
