When doing bulkload , some interactive with zookeeper to getting region key
range may be cost more time.
In multithreads enviorment, the duration maybe cost 5 minute or more.
>From the executor log, like 'Reading reply sessionid:0x262fb37f4a07080 ,
>packet:: clientPath:null server ...' contents appear many times.
It likely to provide new method for bulkload, caching the key range outside
