org.apache.hadoop.hbase.client.HBaseAdmin.move()
Move the region r to dest. @param encodedRegionName The encoded region name; i.e. the hash that makesup the region name suffix: e.g. if regionname is TestTable,0094429456,1289497600452.527db22f95c8a9e0116f0cc13c680396., then the encoded region name is: 527db22f95c8a9e0116f0cc13c680396. @param destServerName The servername of the destination regionserver. Ifpassed the empty byte array we'll assign to a random server. A server name is made of host, port and startcode. Here is an example: host187.example.com,60020,1289493121758 @throws UnknownRegionException Thrown if we can't find a region namedencodedRegionName @throws ZooKeeperConnectionException @throws MasterNotRunningException
