Craig Hawco commented on STORM-2194:
------------------------------------
I attached a scrubbed thread dump showing the issue.
This worker should have 24 spout threads, and 24 b-0 threads, however we can
see that one of the b-0 threads has died, but left the worker running:
{code}
Sulla:Desktop chawco$ grep spout- scrubbed-thread-dump.txt | grep -v SendThread
| grep -v EventThread | wc -l
24
Sulla:Desktop chawco$ grep b-0- scrubbed-thread-dump.txt | wc -l
23
Sulla:Desktop chawco$
{code}
> ReportErrorAndDie doesn't always die
> ------------------------------------

> Key: STORM-2194
> URL: https://issues.apache.org/jira/browse/STORM-2194
> Project: Apache Storm
> Issue Type: Bug
> Components: storm-core
> Affects Versions: 2.0.0, 1.0.2
> Reporter: Craig Hawco
> Attachments: scrubbed-thread-dump.txt
>
> Time Spent: 20m
> Remaining Estimate: 0h

> I've been trying to track down a cause of some of our issues with some
> exceptions leaving Storm workers in a zombified state for some time. I
> believe I've isolated the bug to the behaviour in
> :report-error-and-die/reportErrorAndDie in the executor. Essentially:
> {code}
> :report-error-and-die (fn [error]
> (try
> ((:report-error <>) error)
> (catch Exception e
> (log-message "Error while reporting error to
> cluster, proceeding with shutdown")))
> (if (or
> (exception-cause? InterruptedException
> error)
> (exception-cause?
> java.io.InterruptedIOException error))
> (log-message "Got interrupted excpetion
> shutting thread down...")
> ((:suicide-fn <>))))
> {code}
> has the grouping for the if statement slightly wrong. It shouldn't log OR die
> from InterruptedException/InterruptedIOException, but it should log under
> that condition, and ALWAYS die.
> Basically:
> {code}
> :report-error-and-die (fn [error]
> (try
> ((:report-error <>) error)
> (catch Exception e
> (log-message "Error while reporting error to
> cluster, proceeding with shutdown")))
> (if (or
> (exception-cause? InterruptedException
> error)
> (exception-cause?
> java.io.InterruptedIOException error))
> (log-message "Got interrupted excpetion
> shutting thread down..."))
> ((:suicide-fn <>)))
> {code}
> After digging into the Java port of this code, it looks like a different bug
> was introduced while porting:
> {code}
> if (Utils.exceptionCauseIsInstanceOf(InterruptedException.class, e)
> ||
> Utils.exceptionCauseIsInstanceOf(java.io.InterruptedIOException.class, e)) {
> LOG.info("Got interrupted exception shutting thread down...");
> suicideFn.run();
> }
> {code}
> Was how this was initially ported, and STORM-2142 changed this to:
> {code}
> if (Utils.exceptionCauseIsInstanceOf(InterruptedException.class, e)
> ||
> Utils.exceptionCauseIsInstanceOf(java.io.InterruptedIOException.class, e)) {
> LOG.info("Got interrupted exception shutting thread down...");
> } else {
> suicideFn.run();
> }
> {code}
> However, I believe the correct port is as described above:
> {code}
> if (Utils.exceptionCauseIsInstanceOf(InterruptedException.class, e)
> ||
> Utils.exceptionCauseIsInstanceOf(java.io.InterruptedIOException.class, e)) {
> LOG.info("Got interrupted exception shutting thread down...");
> }
> suicideFn.run();
> {code}
> I'll look into providing patches for the 1.x and 2.x branches shortly.
