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
{code}
hbase shell> disable 'tableName'
hbase shell> snapshot 'tableName', 'tableSnapshot'
hbase shell> clone 'tableSnapshot', 'newTableName'
hbase shell> delete_snapshot 'tableSnapshot'
{code}
{code}
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)
}
{code}
