Subject Re: request for mapreduce with hbase examples
Date Thu, 11 Feb 2010 20:38:39 GMT
I was under the impression that you could read from/write to an hbase  
table from within a mapreduce job.  Import and Export look like  
methods for reading HDFS files into hbase and dumping hbase into an  
HDFS file.
