Vladimir Tarasov updated MAPREDUCE-6832:
----------------------------------------
Priority: Critical (was: Major)
> Counter name is truncated regardless the configuration
> ------------------------------------------------------
>
> Key: MAPREDUCE-6832
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6832
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Environment: hadoop version
> Hadoop 2.6.0-cdh5.8.0
> Subversion http://github.com/cloudera/hadoop -r
> 042da8b868a212c843bcbf3594519dd26e816e79
> Compiled by jenkins on 2016-07-12T22:55Z
> Compiled with protoc 2.5.0
> From source with checksum 2b6c319ecc19f118d6e1c823175717b5
> This command was run using /usr/lib/hadoop/hadoop-common-2.6.0-cdh5.8.0.jar
> Reporter: Vladimir Tarasov
> Priority: Critical
>
> For now I have hadoop job which creates counters with pretty big name. For
> example, the following one:
> stats.counters.server-name.job.job-name.mapper.site.site-name.qualifier.qualifier-name.super-long-string-which-is-not-quantity-within-standard-limits.
> This counter is truncated on web interface and is returned truncated by
> getName() method. I've found out that hadoop have limitations on the counter
> max name and mapreduce.job.counters.counter.name.max is for configuring this
> limit. So I incremented this to 500 and web interface now shows full counter
> name. But getName() of the counter still returns truncated name.
> This seems like a bug as result of getName() call should be consistent.
