Michael Weng commented on HBASE-4179:
-------------------------------------
The root cause is due to the API change between hadoop 0.20-append and hadoop
0.22.
In 0.20-append:
public void driver(String[] args) throws Throwable
In 0.22:
public int driver(String[] args) throws Throwable
Proposed fix:
using getMethod at run time instead of invoke the function directly.
> Failed to run RowCounter on top of Hadoop branch-0.22
