Thank you Samir,
I am using version 0.98.
In case of a snapshot I cannot pre-create the target table. Like, I may want to
specify the more pre-splits for target table than the source table. Is that
possible in an anyway?
Best regards,
Sumit

Subject: Re: Table copies in hbase
Hi Sumit,IMHO snapshots are easiest way to copy tables you need just to steps:
1. create snapshot2. clone snapshot to another table
What version of hbase you are using? Regarding you question what will happen in
case operation fails in case of cloning snapshot i have never experience such
event if snapshot was not corrupted. In case of CopyTable mr i assume that data
will be partially copied. In any case your source tables will be OK.

Hi,
I have a a few tables in hbase which I would like to create copies of. The
tables will be in same cluster.
I wanted to know based on experience, which one of the options is better:
1. copyTable2. snapshot3. Any other?
Besides efficiency aspect, I am also interested in knowing what happens when
the operation fails midway copying from snapshot to destination table. Or when
it fails midway copying to destination table in copyTable option. Would data be
left in inconsistent state?
Thanks,Sumit
