Nick Dimiduk commented on HBASE-12833:
--------------------------------------
bq. the interface changes and the managed/unmanaged connection issues are
separate concerns
Agreed.
I also think that the implementation details of the shell *should not* be
considered a part of our public API contract. Point remains that this is code
we've shipped that folks may be relying on. I asked the question on dev@
yesterday. If no one chimes in, I think we can go forward with the close and
initialize changes for branch-1.0+ (and so long as RM is in agreement).
bq. Do you see any advantages to keeping a mix of managed and unmanaged
connections around?
Not long term, no. However, we will continue to support both for 1.x series as
a backward compatibility consideration.

> TestShell is erring out (timeout) consistently for me. Culprit is OOM cannot
> create native thread. It looks to me like test_table.rb and hbase/table.rb
> are made for leaking connections. table calls
> ConnectionFactory.createConnection() for every table but provides no close()
> method to clean it up. test_table creates a new table with every test.
