I have similar setup to the 0.1.2 but started from a clean startup.
The hadoop 1.7.0 seems to be working fine.
When I start the hbase master I get:
java.lang.reflect.InvocationTargetException but the weirdest thing is
that I also get:
Caused by: java.lang.UnsupportedOperationException: Unable to find
region server interface org.apache.hadoop.hbase.HRegionInterface
and...
Caused by: java.lang.ClassNotFoundException:
org.apache.hadoop.hbase.HRegionInte rface
I copied the log below and below it are my hbase-sirte.xml and
hadoop-site.xml
Thanks

Her is the full hbase log
