denis_makogonAJaeger, i think core-team is well-known with this patch, so no need to ask them multiple times. However, i agreed, this patch looks good14:44

*** todd_dsm has quit IRC15:11
amritha little confused. you +1'ed amcrn's chkin (81914) which would use "service cassandra start" but you said "service cassandra stop" won't work.15:11
amrithI tested with u12.0415:11
amrithpl let me know what the failure was so I can fix and alert amcrn about it as well15:12
denis_makogonamrith, there's problem in precise images15:13
denis_makogonamrith, if start/stop commands would be changed - cassandra would not work inside integration15:14
denis_makogonthat's all15:14
amrithso I'm confused by one thing. if "service start" is +1'ed how come "service stop" is -1'ed. admittedly I'm new here so please bear with the silly question(s)15:15

*** eghobo has joined #openstack-trove15:16
amrithto be clear, the +1 on amcrn's chkin by you (https://review.openstack.org/#/c/81914/) seems inconsistent with your statement here or the -1 on my chkin https://review.openstack.org/#/c/82080/15:16
denis_makogonamrith, different approaches in bug description15:17
denis_makogonamrith, please read Auston's bug report15:17
amrithI read it15:17
amrithand asked him about fixing stop as well15:17
amrithand he opined that it was 'out of scope'.15:18
*** kevinconway has joined #openstack-trove15:18
amrithso what you appear to be saying is that you would rather cassandra be started with "service start" but stopped with "kill"?15:18
hub_caplol that sounds goofy15:19
amrithi agree15:19
amrithand I'm not sure what's in the bug report that you are specifically alluding to. at issue is the fact that cassandra was being started in the wrong process group and hence the change to service start15:19
denis_makogonamrith, kill would work always instead of service15:20
hub_capdenis_makogon: does service stop not kill c*?15:20
hub_capas a operator15:20
hub_capi NEVER use kill15:20
hub_capunless service stop is haning15:20
hub_capNEVER15:20
amrithkill is not a good way to stop a service of any kind15:20
hub_cap*hanging15:20
hub_capno its not amrith :)15:20
hub_capits teh WORST way15:20
hub_capaka last resort15:21
kevinconwayi have an alias call stop that is pkill -9 -f *15:21
amrithSIGTERM leaves your handler in theuncomfortable position of having to deal with a restricted set of 'safe things' to do15:21
hub_capLOL kevinconway15:21
denis_makogonhub_cap, first approach of kill was - make it work under integration, but i agree that it should be "service" but it would not work with 12.04 LTS15:21
hub_capkevinconway: is it alias ls=pkill...15:21
amrithhencec an inband message (which is what a service stop would do) or in the mogo case would be mongodb --shutdown would be the proper way to do things15:21
amrithif you wanted to operate a service in produciton15:21
hub_capdenis_makogon: what do u mean? "would not work with 12.04"?15:22
hub_capis there a bug in ubuntu tracked for it?15:22
denis_makogonhub_cap, under trove-integration deployment and kick-start15:22
hub_capif there is a good reason we _have_ to use kill, we can... but if i was an operator id see that and immed not want to use trove15:22
hub_cap:)15:22
amrithdenis_makogan: please let me know how "service start" works in integation and I'll make it work identically in "service stop"15:22
denis_makogonamrith, prof. ?15:23
denis_makogonamrith, please share start log15:23
amrithsorry, unfamiliar with your acronym15:23
denis_makogonamrith, sorry, misspell, proof15:23
amrithhappy to send you the doc page ... one second15:24
amrithby the way, did you run "service cassandra start" somewhere? did it work?15:24

*** todd_dsm has joined #openstack-trove15:27
denis_makogonamrith, i tried multiple times different ways to start/stop cassandra15:27
amrithso, please do tell me why it makes sense to +1 a "service cassandra start" but -1 a "service cassandra stop" ;)15:27

denis_makogonamrith, i +1 first patch because it fixes one type of error, that was hidden deeply, and Auston did that well, but "This is excessively harsh" is not the reason for changing stop command15:30
denis_makogonamrith, i'm gonna re-verify both patches, and possibly re-define marks for them, unless that, it'll stay as it is15:31

amrithViswaV: I concur with your observations in your comments on 82080. See my paste output from http://paste.openstack.org/show/74160/17:32
amrithI think we're saying the same thing17:32
ViswaVamrith: yup17:32
ViswaVI have additional comment on https://github.com/openstack/trove/blob/master/trove/guestagent/datastore/cassandra/system.py#L37 .  which seems to have been overlooked as well.17:34
ViswaVI think this cmd (CASSANDRA_KILL) is used at https://github.com/openstack/trove/blob/master/trove/guestagent/datastore/cassandra/service.py#L83 .  It seems reasonable that you would want to kill Cassandra if the service start did not result in proper startup of the process.17:34
ViswaV But the same argument about overarching 'killall java' applies here as well. If you had to kill, kill the precise process.  Not all java. Since you are handling service stop in your patch set, it might be good to handle this case properly as well in the same patch17:35

*** mattgriffin has joined #openstack-trove18:11
amrithViswaV: While CASSANDRA_KILL is used in the place you referenced, the reason I made the change is two fold.18:11
amritha) service cassandra stop does pretty much the same thing18:11
amrithit does it in a more orderly way using start-stop-daemon18:12
amrithb) more importantly, if cassandra uses some other method at a later time, you get that automatically18:12
amrithWhat we know from the doc is that they recommend using service cassandra stop for a cluster18:12
amrithsimilar to service cassandra start to start it in the first place.18:12
amrithhope that makes sense.18:12
ViswaVamrith: I am totally with you .   When stopping  "service stop cassandra" should be used and not killall java as I mentioned in the comment. What I also want bring attention to, is that elsewhere in the same file CASSANDRA_KILL is defined (which also uses 'killall java').  My point is that as part of the same patch set, may be that command can also be fixed to use a more precise kill command  instead of 'killall java'.   You could debate18:16
ViswaV whether CASSANDRA_KILL cmd is needed at all. May be not. But I can see (based on where it is being used), that it is to be used in the context when 'start service'  did not result in proper starting, but a hanged process (which may not be terminated by issuing service stop).  So I can see the justification for that. Just wanted to ensure that cmd is also made safe  (kill cassandra's java process and not killall java)18:16
