Subject [jira] [Commented] (ACCUMULO-2787) Accumulo too strict about max files
Date Tue, 10 Jun 2014 14:06:01 GMT


Josh Elser commented on ACCUMULO-2787:

So, the actual amount of file handles needed by a tserver would be relative to the number
of user connections, number of connections from the master, number of connections from other
tservers (bulk load?), and number of rfiles being hosted by that tserver?

Is it possible to justify the value with a back of the envelope number? Picking a number out
of the air and warning about it instead of this number just makes me feel like we'll have
this same discussion in 6mos except in the other direction (not strict enough about needing
more file handles).

like 10k is probably fine.
> We should lower the WARN threshold.
