Hi,
I have no issues to build and start HBase from HBase code.
But when I try from BigTop, at stratup I get a class not found error:
[root@hbr101 ~]# /etc/init.d/hbase-master start
starting master, logging to /var/log/hbase/hbase-hbase-master-hbr101.out
Exception in thread "main" java.lang.NoClassDefFoundError:

Failed to start HBase master daemon. Return value: 1 [FAILED]
If I export the Hadoop and HBase classpath, I'm able to pass this, but the
I face another ClassNotFound exception on the HBase side.
export HBASE_CLASSPATH=`hbase classpath`:`hadoop classpath`

I'm wondering, has anyone try to build HBase 0.98.4+ with BigTop trunk and
has been able to start it? I checked and class is on the metric jar, and
the jar in there on the CP. so I'm wondering where this is coming from and
still investigating. If I found anything, I will open a JIRA and provide
the details...
Thanks,
JM
