Subject [jira] [Commented] (HBASE-4275) RS should communicate fatal "aborts" back to the master
Date Tue, 30 Aug 2011 03:00:39 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4275?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13093392#comment-13093392

Ted Yu commented on HBASE-4275:

This is a useful feature.

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

> 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.
