Christos Dosis commented on HBASE-26451:
----------------------------------------
Hi, [~psomogyi] thanks for your response.
The same happens also for additional lines?
After restoration, any new lines introduced after a backup was taken are still
there and not deleted?
In such a case, MapReduce Import doesn't have any effect on tsdb tables,
correct?
I am trying to compare MapReduce with Snapshot Export/Import tasks.
Snapshots are working differently and seem that we can import a table as it was
when the backup was taken.
Thanks in advance!

> Hi Hbase support team,
>
> While using the MapReduce job with export/import commands we have the below
> behaviour.
>
> {+}Step1{+}: I have a hbase table(tsdb) with 3 rows. and export the table
> like below:
> /opt/hbase/bin/hbase org.apache.hadoop.hbase.mapreduce.Export tsdb
> file:///opt/hbase/backup/tsdb
> {+}Step2{+}: Then I delete 1 row.
> {+}Step3{+}: Then I import tsdb table from the exported data from Step 1.
> /opt/hbase/bin/hbase org.apache.hadoop.hbase.mapreduce.Import tsdb
> file:///opt/hbase/backup/tsdb
>
> There are still only 2 rows in the table. Is this a valid behaviour?

> Br,
