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,

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.
