Description

TestAdmin1#testHFileReplication has been failing against hadoop-1 since (at least) this build:
https://builds.apache.org/job/HBase-0.98-on-Hadoop-1.1/1082/testReport/org.apache.hadoop.hbase.client/TestAdmin1/testHFileReplication/

The cause is that the following method is absent in hadoop-1 (in FSUtils#create()):

          return (FSDataOutputStream) (DistributedFileSystem.class.getDeclaredMethod("create",
            Path.class, FsPermission.class, boolean.class, int.class, short.class, long.class,
            Progressable.class, InetSocketAddress[].class).invoke(backingFs, path, perm, true,

The following fallback doesn't take replication parameter:

    return create(fs, path, perm, true);

leading to DFS replication being 3 for the column family which should have DFS replication of 1
