Hbase import/export change number of rows

[OM PARKASH Nain]

I am using Hbase export using command.

  hbase org.apache.hadoop.hbase.mapreduce.Export "Table1" "hdfs path"

Then I use import command from HDFS to Hbase Table;

hbase org.apache.hadoop.hbase.mapreduce.Import "hdfs path" "Table2"

Then I count number of row in both tables, I found mismatch number of rows

Table1:8301 Table2:8032

Please define what goes wrong with my system.
