Robert Joseph Evans commented on STORM-70:
------------------------------------------
I am not really sure that that is the cause of the change in unit-test time
(but it could be). I ran some tests on RHEL_6 on VM and the time to run all of
the tests went from 2:30 to about 3:30. The max memory utilization appears to
have gone down from 850MB resident to about 750MB resident. But it wasn't
extra computation happening, it was all in wall clock time, like the ZK client
is waiting longer for something to happen now (I ran this several times and
they are all fairly consistent).
Master:
real 2m29.159s
user 1m59.253s
sys 0m22.703s
STORM-70:
real 3m26.744s
user 1m52.505s
sys 0m24.081s
I'll try to see if I can figure out what is happening. Without these changes
though, ZK does not work properly with Kerberos.
