Hello Edward:
The HDFS2.x problem is caused by the protobuffer version.
After I upgrade protobufer2.4a.jar to protobuf-java-2.5.0.jar in $hamahome/lib,
that problem is gone(So it should relate to mavn build issue, do I need to log
an issue and fix it there?)
Also I have tested with hadoop 2.0.3 alpha, itself has blocking issue, even
cannot run the mapreduce job. So currently I do not have a hadoop 2.x version
which can run with hama.
May be we just use yarn 2.2.0 as code base.
For hoya, it is still under developing, which version do they want to support
hama?
And after fix hdfs, zookeeper has error now
