Jonathan Hsieh commented on HBASE-5680:
---------------------------------------
The master starts on top of hadoop 0.23.x
apache 0.92.1 recompiled with the security profile *on* (-Psecurity) and with
-Dhadoop.profile=23
apache 0.94.0rc0 recompiled with the security profile *on* (-Psecurity) and
with -Dhadoop.profile=23
The master fails on top of hadoop 0.23.x with the class not found error in
these cases:
apache 0.92.1 right out of tarball
apache 0.92.1 with the security profile *off* with -Dhadoop.profile=23
apache 0.94.0rc0 right out of tarball.
apache 0.94.0rc0 security right out of tarball.
apache 0.94.0rc0 with the security profile *off* with -Dhadoop.profile=23
> Hbase94 and Hbase 92.2 is not compatible with the Hadoop 23.1
