[jira] [Created] (HDFS-2782) HA: Support multiple shared edits dirs
HA: Support multiple shared edits dirs
--------------------------------------
Key: HDFS-2782
URL: https://issues.apache.org/jira/browse/HDFS-2782
Project: Hadoop HDFS
Issue Type: Sub-task
Components: ha
Affects Versions: HA branch (HDFS-1623)
Reporter: Eli Collins
Assignee: Eli Collins
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.

-------------------------------
Resolution: Won't Fix

Target Version/s: (was: 0.24.0)
Given QJM (HDFS-3077) IMO this is no longer worth considering.
