I tried applying the patch to the hbase source code hbase 0.20.2 and I get the errors below. Do you know if this needs to be applied to a specific hbase version. Is there a version which works with 0.20.2 or later ?? Basically HRegionServer and HTable patching fails.

The index is stored in a separate table, but the index is managed for you. I don't think you can do an arbitrary "in" query, though. If the keys that you want to include in the "in" are reasonably close neighbors, you could do a scan and skip ones that are uninteresting. You could also try a batch Get by applying a separate patch, see http://issues.apache.org/jira/browse/HBASE-1845.
