hi all,

I built a tarball installation from hbase-core-trunk using:

mvn -Dhadoop.profile=2.0 package install assembly:assembly -DskipTests

Then I used the tarball to start an Hbase cluster on top of HDFS 2.0.
however, the master failed to start with following exception:

Seems like the class org.apache.hadoop.metrics2.lib.MetricMutable could not
be found.

Could somebody please guide me how to resolve this problem?

Many thanks,
Thanh

Strange.
BaseMetricsSourceImpl class in hbase-hadoop2-compat module doesn't refer to
MetricMutable directly.

That's weird MetricMutable is the 1.0.X version. It looks like you are
trying to run a 1.0 version tar ball on a 2.0 hdfs.  When you look into
your tar ball directory is there a hbase-hadoop2-compat ?

Yes there is a hbase-hadoop2-compat.

I think i figured out the problem. The hadoop 1.0 tar is still in my
~/.m2/repo folder, so it was loaded into the classpath.

Many thanks,
Thanh
