Subject [jira] [Commented] (CRUNCH-330) Use of multiple output counters can be disabled in configuration.
Date Thu, 23 Jan 2014 21:17:37 GMT


Dominique Dierickx commented on CRUNCH-330:

I see how that makes the code simpler and agree that the overhead of the conditional will
be minimal. I also guess there is no need to just be able to disable/enable some namedoutput
counters? If so I'm very happy with this patch.

> We're having some trouble with the amount of counters that Crunch creates
> when writing to a lot of different output files (slightly more than 120).
> This wouldn't be an issue if we were able to configure the maximum number

> version of Hadoop, doing this is not an option and we are required to patch
> Crunch locally when using a new release to leave out the counters.
> I'm not saying the counters should be removed but maybe it is an option to
> make them configurable without paying too much of a performance penalty?
> I will implement this functionality and submit a patch.
