HConnection.locateRegions returns null

[Lyska Anton]

Hi all,

I want to write simple tool for rebalancing regions in cluster.
For that I need current location of all regions.
I've found method HConnection.locateRegions(tableName), but it always returns 
null.
Also, i've tried to call HConnection.locateRegion(regionName), and it returns 
null too.

sample code:

        Configuration config = HBaseConfiguration.create();
        config.set("hbase.zookeeper.quorum", host);

        HConnection connection = HConnectionManager.createConnection(config);
        List<HRegionLocation> locations = connection.locateRegions(tableName);  
//return null here

HBase Version    0.92.1-cdh4.1.2

Thanks in advance.
