Subject Unable to run map reduce in HBase
Date Fri, 28 Nov 2014 06:03:41 GMT
Hi, 

I am importing a csv file into HBase using the command bin/hbase 
org.apache.hadoop.hbase.mapreduce.ImportTsv 

When I execute the this map reduce program I am getting the following 
error. I am using Hadoop 2.4.1 and HBase 0.98.8-hadoop2

I have set export JAVA_OPTS="-Xms1024m -Xmx10240m" in .bashrc, the server 
has 32 GB of RAM.
