Ivan Kelly updated HDFS-2018:
-----------------------------
Attachment: HDFS-2018.diff
New patch. Applies on top of my HDFS-2227 patch. This is the third part of
split proposed in Todd's comment avoid, which replaces the LogPlan with
FSEditLog#selectInputStreams
For review it may be easier to look at my github tree, as it shows this in
three changesets.
1. Adding the functionallity to FSEditLog & FileJournalManager to select input
stream.
2. Removal of LoadPlan.
3. Fix up of recovery.

> Currently in the HDFS-1073 branch, the code for creating output streams is in
> FileJournalManager and the code for input streams is in the inspectors. This
> change does a number of things.
> - Input and Output streams are now created by the JournalManager.
> - FSImageStorageInspectors now deals with URIs when referring to edit logs
> - Recovery of inprogress logs is performed by counting the number of
> transactions instead of looking at the length of the file.
> The patch for this applies on top of the HDFS-1073 branch + HDFS-2003 patch.
