[ nitin@nitin-ubuntu:~ ]#  hbase org.apache.hadoop.hbase.mapreduce.Export HBASEEXPORTTABLE DUMP

STEP 2

IMPORT :- 

Import is a utility that will load data that has been exported back into HBase. Invoke via:



[ nitin@nitin-ubuntu:~ ]# hbase org.apache.hadoop.hbase.mapreduce.Import                   <tablename> <inputdir>

[ nitin@nitin-ubuntu:~ ]#  hbase org.apache.hadoop.hbase.mapreduce.Import HBASEIMPORTABLE DUMP
