> 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.
