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??? -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Stack Sent: Monday, December 27, 2010 9:45 PM To: [email protected]; [email protected] Cc: [email protected] Subject: Re: is hbase 0.20.6 compatible with new hadoop 0.21.0 ?
