Subject: Re: [SURVEY] What version of Storm are you using?

Upgraded one of our cluster from 0.10 to 1.0.1 a month back and running successfully without any issues. Its worth all the time spent on the upgrade as the new features are awesome for debugging and for everybody.


Another critical cluster is already upgraded from 0.9.4 to 1.0.1 and will be live soon in matter of days.


Upgrade was very straight forward as most of the changes are in pom.xml and we mainly use the storm-kafka spout with kafka 0.9.X client libs and kafka 0.9.X brokers.



1) Only blocker was log4j2 change as mentioned above. We were using scribe-logback for logging.

So we ended up creating our own scribe log4j2 custom appender which was anyway needed for any type of applications within our team.



2) One issue which we are facing right now is killing the topology from cli some times does not kill the worker in 1.0.1 though the UI says KILLED.Though there is a workaround for this(like clearing nimbus state by hand) but still looking for a clean solution(considering to go to 1.0.2 for this plus other stability fixes it has). I saw couple of JIRAs but not sure whether those made it 1.0.2


Overall +1 for storm 1.0.x upgrade. Lot of useful features which makes everybody's life easier especially ops team.

Andrew and Erik, please feel free to post the issue to dev@ whenever you meet the issue from streamparse, storm-mesos, and etc. which might be cause of upstream so that Storm dev. community can help if possible.

Erik, re: this issue, "blocked by us dealing with mysterious Storm Worker process heartbeat failures", do you have any topo's @ Groupon using ShellSpout (multi-lang)?

If so, the patch/resolution in STORM-1928 (released in 1.0.2, see JIRA for details) may be helpful.

Side note for users waiting stable version of 1.x: 1.0.2 is worth to try out since it's well tested, and fixes various critical bugs users met.

Groupon is using 0.9.6.


Switching to 0.10.0 or 1.0+ will take us more time largely because of the "logback to log4j 2" change in 0.10.  We have a bunch of internal teams using a library for logging which is based on logback, and it's definitely going to be herding cats to get them to upgrade their topologies.


We are also responsible for the storm-mesos framework, which we will hopefully come back to adding support for 1.0+ next month on.   Spending time on that is currently blocked by us dealing with mysterious Storm Worker process heartbeat failures.
