> 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.
