Todd Lipcon updated HBASE-4275:
-------------------------------
Attachment: 0005-HBASE-4275.-Report-fatals-to-HMaster.patch
Here's a patch which adds the new RPC.
The master logs it locally and also keeps a ring-buffer of such log messages,
constrained to 1MB by default.
I've tested this on a cluster in coordination with HBASE-4292 (which displays
the ring buffer) and it's very useful for debugging.
The RS-abort behavior should probably get its own unit test before commit (or
add some assertions to existing tests)
> RS should communicate fatal "aborts" back to the master

> When a region server aborts, it should attempt to send an RPC to the master
> that contains (a) the reason for aborting, and (b) the last several KB of log
> messages, if available. This should help a lot in debugging.
