--------------------------------

"Too many open files"

We're using quite a lot of threads here:
hbase.ResourceChecker(145): after 
client.TestInstantSchemaChange#testInstantSchemaJanitor: 343 threads (was 117), 
863 file descriptors (was 600). 6 connections,  -thread leak?-  -file handle 
leak?- 

The patch can be committed imho, but I wonder why we have so many threads & 
open files.
                
> HConnection.create(final Connection conf) does not clone, it creates a new 
> Configuration reading *.xmls and then does a merge.
