Nicolas Liochon commented on HBASE-9116:
----------------------------------------

I haven't run the tool, just read the code.
Seems ok, some nits:

bq. long startTime = System.currentTimeMillis();
Please use EnvironmentEdge

bq. * Copyright 2011 The Apache Software Foundation
No date anymore on licenses

bq.    // TODO Auto-generated method stub
Should be removed if we're fine with the standard generation

also fix the mappings if needed. Such a tool exists in the 0.89-fb branch. Will port it over
to trunk/0.95.
