wolfgang hoschek commented on SOLR-5605:
----------------------------------------
Thanks for getting to the bottom of this!
Looks like we'll now be good on upgrade to argparse4j-0.4.3, except we'll also
need to apply CDH-16434 to MapReduceIndexerTool.java because there's a change
related to flushing in 0.4.2:
- parser.printHelp(new PrintWriter(System.out));
+ parser.printHelp();
Otherwise some of the --help text doesn't show up in the output :-(

> URL: https://issues.apache.org/jira/browse/SOLR-5605
> Project: Solr
> Issue Type: Bug
> Reporter: Hoss Man
>
> I noticed a randomized failure in MapReduceIndexerToolArgumentParserTest
> which is reproducible with any seed -- all that matters is the locale.
> The problem sounded familiar, and a quick search verified that jenkins has in
> fact hit this a couple of times in the past -- Uwe commented on the list that
> this is due to a real problem in one of the third-party dependencies (that
> does the argument parsing) that will affect usage on some systems.
> If working around the bug in the arg parsing lib isn't feasible,
> MapReduceIndexerTool should fail cleanly if the locale isn't one we know is
> "supported"
