Hbase 0.98 import table is not working

Question

I have successfully exported a table in hbase version 0.98 using the following command (Using MapReduce API)

./hbase -Dhbase.export.version=0.98 org.apache.hadoop.hbase.mapreduce.Export testtable file:///home/test/test/hbase-0.98.4-hadoop2/bin/2

It created a folder in name ' 2 ' with the map reduce data of parts and success are being generated successfully and when i open the parts-000 file that has the data of the testtable.

But I try to import using import command,

./hbase -Dhbase.import.version=0.98 org.apache.hadoop.hbase.mapreduce.Import testtable file:///home/test/test/hbase-0.98.4-hadoop2/bin/2

It successfully runs ,

Output:

BUT THE testtable doesnot have any entries in it!

What the mistake am making here,, Is there any other way of doing an export and import.

Answer 1

First create a new Hbase table and then run the Import utility.
