| Move a region. Optionally specify target regionserver else we choose one |
| at random. NOTE: You pass the encoded region name, not the region name so |
| this command is a little different to the others. The encoded region name |
| is the hash suffix on region names: e.g. if the region name were |
| TestTable,0094429456,1289497600452.527db22f95c8a9e0116f0cc13c680396. then |
| the encoded region name portion is 527db22f95c8a9e0116f0cc13c680396 |
| A server name is its host, port plus startcode. For example: |
| host187.example.com,60020,1289493121758 |
| Examples: |
| |
| hbase> move 'ENCODED_REGIONNAME' |
| hbase> move 'ENCODED_REGIONNAME', 'SERVER_NAME' |
| EOF |
