Hi all,

I have copied a Hbase table from a different cluster, but while copying it i have forgotten to mention the number of regions. Now while trying to scan or get something from the Hbase table it is taking a huge chunk of time.

By default it has taken two regions, now only two mappers were able work on it.

Which is making my data retrieval very expensive.

Now i want to increase the number of regions without losing my data in the table.

How can i do it? 

 

Any help is apperciated.
