Description

The current thrift interface has the getTableRegions() interface like below.

  list<TRegionInfo> getTableRegions(
    /** table name */
    1:Text tableName)
    throws (1:IOError io)

struct TRegionInfo {
  1:Text startKey,
  2:Text endKey,
  3:i64 id,
  4:Text name,
  5:byte version
}

But the method don't have the region location information (where the region is located).

I want to add the Thrift interfaces like below in HTable.java.

public Map<HRegionInfo, HServerAddress> getRegionsInfo() throws IOException

public HRegionLocation getRegionLocation(final String row)
