Subject Re: anyone relying on hadoop1 still?
Date Thu, 25 Sep 2014 21:22:30 GMT
Mostly its the use of hadoop metrics2 that has to change, as they change
the backing methods. If you are interested, take the hbase compatibility
layer <https://github.com/apache/hbase/tree/master/hbase-hadoop-compat/> to
see most of where HBase shims things.
