You can also use HTable#getRegionLocations(): public NavigableMap getRegionLocations() throwsIOException { FYI On Wed, Aug 28, 2013 at 6:12 AM, Surendra , Manchikanti < surendra.manchika...@gmail.com> wrote: > List< > http://docs.oracle.com/javase/6/docs/api/java/util/List.html?is-external=t

Re: Is it possible to get the region count of a table via an API?

To check how regions you have in a table (and possibly what they are) HBaseAdmin#getTableRegions. In order to split the table you can use HBAdmin#split

Is it possible to get the region count of a table via an API?

Hi all, I know what we can go over to the HBase UI and make a split on our table so that it will be distributed over the cluster.. Is there a way to know it via an API and to possibly change it? This is to know how many map tasks run on our table before we actually run the MR job.. -- Regards- Pav
