bc Wong updated MAPREDUCE-5492:
-------------------------------
Assignee: bc Wong
The IllegalStateException is caused by the TT's attempt to reuse a committed
HttpServletResponse to send an error. To highlight the offending code path in
TaskTracker#doGet:
{noformat}
try {
outStream = response.getOutputStream();
outStream.flush(); // <-- This commit/finalize the response
} catch (...) {
response.sendError(); // <-- Illegal. Shouldn't reuse a committed response
}
{noformat}
> Suppress expected log output stated on MAPREDUCE-5
> --------------------------------------------------

> Key: MAPREDUCE-5492
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-5492
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Affects Versions: 0.20.2
> Reporter: Harsh J
> Assignee: bc Wong
> Priority: Trivial
>
> Jetty in MR1 may produce an expected EOFException during its operation that
> we shouldn't log out in ERROR form.
> This shouldn't affect MR2, however, as it uses Netty.
> See MAPREDUCE-5 (Jothi's comments) for more info.
