Hi all,
I am having the cloudera hadoop CDH3 - pseudo distributed environment. I am
trying to upload the bulk of data into the hbase-0.89 using the Map Reduce
program. I am not interested in the command line tools in hbase (importtsv &
completebulkload). I got the Sample Map Reduce program from the Hbase-0.20.6
API document.
When I executed the Map Reduce program using the Hadoop, I am getting the
following exception.
java.io.IOException: table is null
at BulkImport$InnerMap.map(BulkImport.java:44)

.
Guess I am missing the some of the settings in the Hbase or hadoop.
Please suggest me regarding this problem. I am facing the same problem when
I executed the Importtsv tool.
