Description

Add a section "how to rename a table" in the doc book.

The current easy solution without adding extra code in 94/95 is to use snapshots

hbase shell> disable 'tableName'
hbase shell> snapshot 'tableName', 'tableSnapshot'
hbase shell> clone 'tableSnapshot', 'newTableName'
hbase shell> delete_snapshot 'tableSnapshot'

void rename(HBaseAdmin admin, String oldTableName, String newTableName) {
    String snapshotName = randomName();
    admin.snapshot(snapshotName, oldTableName);
    admin.cloneSnapshot(snapshotName, newTableName);
    admin.deleteSnapshot(snapshotName);
    admin.deleteTable(oldTableName)
}
