Jeffrey Zhong updated HBASE-12103:
----------------------------------
Description:
The reason of back porting is that 0.96+ HBase doesn't support HFileV1 format
anymore. While HFileV1Detector in 0.96+, which is supposed to check v1 hfile
before upgrade, can't talk to pre 0.96 cluster because underlying hadoop
doesn't compatible either due to protocol buffer version bump.
After the back port, a user can just download the latest 0.94 HBase tar ball in
a machine, point its config to a 0.94 cluster to check v1 file existance by
running following command:
{code}
./bin/hbase org.apache.hadoop.hbase.util.HFileV1Detector -p <hbase root data
path>
{code}
