Jeffrey Zhong commented on HBASE-9754:
--------------------------------------
Thanks [[email protected]] for looking this! You're so quick. Actually I was
just asking the possibility of back porting this JIRA but you already have the
patch.

I'm not a fan of backporting this. Could we do something narrower to get you
what you need
{quote}
I agree. At least this is needed when I looked at the issue last time. Let me
run some tests early next week with your addendum patch and get back to you.
Thanks.

> Currently we use ThreadLocals to communicate the current readpoint between a
> RegionScanner and the Store\{File}Scanner's down the stack.
> Since ThreadLocals are not cheap we should consider whether it is possible to
> pass the readpoint through the call stack instead.
