Dear all,

       Firstly, thanks for your efforts about hbase/hadoop project, they are
the good projects and give our better understanding and help.
       When we use the hbase, create the htable and do stress testing; find
out some problems. That is , we insert the record into the htable
continually, after a period,  we meet some errors as the following
informations.


count:40186954    ( The record number inserted)

count:40186955    ( The record number inserted)

count:40186956    ( The record number inserted)

count:40186957    ( The record number inserted)

Exception in thread "main"
org.apache.hadoop.hbase.client.RetriesExhaustedException: Trying to contact

        As above shown,  if any problems,  how to do for fixing the
problems. By the way, can send our  some your stress testing results and
give our better suggestions.

      The table used in our testbed shown:

       hbase(main):015:0> describe 'imlogs'

{NAME => 'imlogs', IS_ROOT => 'false', IS_META => 'false', FAMILIES =>
[{NAME => 'reciever', BLOOMFILTER => 'f

alse', VERSIONS => '999999999', COMPRESSION => 'NONE', LENGTH =>

                                                       Best regards

thanks
