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.
