I think there is no need to make it configurable. Other tables are just skipped by the normalizer, they should have at least 3 regions to be considered for normalization. They are updated very rarely, so we can expect split/merge their regions once per month or even less often. > On Окт. 29, 2015, 4:01 п.п., Sid Wagle wrote: > > ambari-metrics/ambari-metrics-timelineservice/conf/unix/ambari-metrics-collector, > > line 92 > > <https://reviews.apache.org/r/39758/diff/2/?file=1112158#file1112158line92> > > > > This should have some timeout value. alter_async is executed asyncronously, in backgound, so start command execution time isn't increased. We don't wait, that's a reason why we can't log if the altering table succeeded or not. If use syncronous alter command, collector start time can take up to 2 minutes. That's a workaround until normalization enabling supported by the Phoenix DDL - Dmytro ----------------------------------------------------------- This is an automatically generated e-mail.
