      Description

      Supporting multiple shared dirs will improve availability (eg see HDFS-2769). You may want to use multiple shared dirs on a single filer (eg for better fault isolation) or because you want to use multiple filers/mounts. Per HDFS-2752 (and HDFS-2735) we need to do things like use the JournalSet in EditLogTailer and add tests.
