---------------------------------------
@Daryn:
Looking at:
http://docs.oracle.com/javase/1.4.2/docs/api/java/lang/Class.html#getDeclaredMethod%28java.lang.String,%20java.lang.Class[]%29
I don't see why getDeclaredMethod wouldn't find the desired method from this.fs
w.r.t. setAccessible(), I didn't include it in patch v1 for this reason.
Then I found that getGetNumCurrentReplicas() was using the call. And:
{code}
public int getNumCurrentReplicas() throws IOException {
./src/hdfs/org/apache/hadoop/hdfs/DFSClient.java
{code}

> HBase currently doesn't work with HDFS federation (hbase.rootdir with a
> client that uses viewfs) because HLog#init uses
> FileSystem#getDefaultBlockSize and getDefaultReplication. These throw an
> exception because there is no default filesystem in a viewfs client so
> there's no way to determine a default block size or replication factor. They
> could use the versions of these methods that take a path, however these were
> introduced in HADOOP-8014 and are not yet available in Hadoop 1.x.
