Subject [jira] [Resolved] (ACCUMULO-3617) unloadTablet log message in TabletServer is spammy w/o purpose
Date Fri, 10 Apr 2015 19:55:12 GMT


Christopher Tubbs resolved ACCUMULO-3617.
       Resolution: Not A Problem
    Fix Version/s:     (was: 1.7.0)

It looks like [~ecn] changed this debug message to a trace message in ACCUMULO-3699 a few
weeks ago, so I'm going to consider this no longer a problem. Please re-open if there is additional
concern about the trace level being too spammy.

> Looking at TabletServer logs, the following message can be overwhelming:
> {noformat}
> 2015-02-24 01:57:34,723 [tserver.TabletServer] DEBUG: Got unloadTablet message from user:
> {noformat}
> This message alone tells us nothing (no context about the tablet(s) requested to be unloaded,
only that there was a request to unload a tablet), and can appear in the log upwards of 20
times a millisecond.
> It might be better if the TabletServer did...
> * Batched log messages "N unloadTablet requests in $duration"
> * Include extent to unload
> * Kill the log message entirely.
