Subject Re: something wrong with hbase mapreduce
Date Wed, 01 Dec 2010 08:24:08 GMT
i found  that if i didnt control  timestamp of the put
mapreduce can run, otherwise just one time mapreduce.
the question is i scan by timestamp  to  get my data
so to put timestamp is my scan thing.

any ideas  ? thanks.
