HBASE-3744 introduced a change in how createTable() works.
By default, sync parameter is false:
public void createTable(HTableDescriptor desc, byte [][] splitKeys)
throws IOException {
createTable(desc, splitKeys, false);
}
because HBaseAdmin.createTableAsync() doesn't pass sync parameter to the
master.
On a Linux machine, TestAdmin passed.
