Ashutosh Chauhan commented on HIVE-5182:
----------------------------------------
I will suggest to add it inside serialize/deserializeObject as well, since we
have caches around these objects. So, if our code is working correctly, this
should not be called more than once per process. Further, if we do see them
getting printed multiple times, we know we got something to fix.
> log more stuff via PerfLogger

> PerfLogger output is useful in understanding perf. There are large gaps in
> it, however, and it's not clear what is going on during these. Some sections
> are large and have no breakdown. It would be nice to add more stuff. At this
> point I'm not certain where exactly, whoever makes the patch (me?) will just
> need to look at the above gaps and fill them in.
