Ted Yu commented on HBASE-4275:
-------------------------------
This is a useful feature.
{code}
+ conf.getLong("hbase.master.rs-fatals-heapsize", 1*1024*1024));
{code}
Should the config be called "hbase.master.rs.fatals.heapsize" ?
{code}
+ String msg = "Region server " + serverInfo + " reported a fatal error:\n"
{code}
If all master needs is a String, probably we should change the type of
HServerInfo parameter accordingly.
{code}
+
+public class TestMemoryBoundedLogMessageBuffer {
{code}
Please add a short description for the test class.
{code}
+ private static final String JP_TEXT = "こんにちは";
{code}
Wonderful, I should learn Japanese :-)
> 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.
