Subject about HTable and HConnectionImplementation thread-safety
Date Wed, 11 May 2011 09:39:02 GMT
I understand HTable is not thread-safe. How about 
HConnectionImplementation? I presume it is thread-safe, because 
otherwise creating a HTable for each thread will only work when each 
thread uses it's own Configuration. (Since Configuration is mapped to a 
HConnectionImplementation). So, how does it exactly achieve 
thread-safety? For example, will N threads result in N zookeeper 

Secondly, are there any plans to improve HTable thread-safety / 
efficiency? I'm aware of asynchbase, but I think it would be very nice 
to have an efficient implementation out of the box.
