I'm likely not setting capillary.kafka.zkroot or capillary.storm.zkroot correctly, resulting in the below exception.

I've tried setting these parameters a number of times, using different paths - nothing seems to make a difference.

We're running two topologies. One is using trident, the other is not. We're running zookeeper-3.4.5, apache-storm-0.9.2-incubating and kafka_2.8.0-0.8.1.

We're not setting a storm or kafka root, so I would think whatever the app defaults to should be correct. Here's the zookeeper structure.

[zk: localhost:2181(CONNECTED) 0] ls /
[transactional, realtimeroot, zookeeper, admin, consumers, config, controller, storm, brokers, controller_epoch]

Note that realtimeroot is the spout-root for one of the topos. The trident topo seems to store it's data in /transactional/topo_name/user

Here's the error:

Hey there!

Sounds like I might not be doing things the right way for Trident-based spouts. That's good to know. We're not using Trident so to fix this I might need your help to test in the futre. Thanks for taking the time to poke at Zookeeper for me!

I'll set up a Trident topology locally and work on support. I'll update this ticket when I get it done.

I tried to bypass not supplying a root by replacing "//" with "/" in the zookeeper path.

@rja1 I updated the paths so that they are trident compatible, see my fork here: https://github.com/shareaholic/capillary

I didn't do anything wrt a startup flag to differentiate between storm/trident. But that shouldn't be that difficult.

Apologies for the delay and thanks again for the work.

It's not working for me.... not sure if I'm doing something wrong or not.
See the exception below. Note that we're running two topologies. One uses
a traditional kafka spout, the other uses trident. Both connect to the
same zookeeper cluster. I may be setting my roots incorrectly, although
I've tried numerous combinations, none of which seem to work.

Thanks

What I’ve found is that based on the way that the kafka-spout (I’m using the storm external version) uses nodes, and lack of re-tries, I sometimes need to refresh the page a few times before I get a result.  I also made additional updates yesterday, not sure if they have been merged yet.

See error before.

Just to clarify, I'm pulling the latest version here:
https://github.com/keenlabs/capillary/archive/master.zip - md5:
b76175e17ee5728201cd313393159b89 (merged 11 minutes ago)

I'm then building like:

  • unpacking the zip
  • running sbt
  • running dist
  • Grabbing the zip produced and kicking off capillary.

Just wanted to make sure I'm not doing something silly, as I'm sort of a
newb to this.

Thanks,

Rob

Hi.

I am starting Capillary by following command in terminal

bin/capillary -Dcapillary.zookeepers=192.168.51.98:2181

Please note that Kafka is at machine 1, Zookeeper is at machine 2 and storm is at machine 3. And i am running Capillary from a different machine, suppose machine 4. Initially I was not providing any configuration for kafka.zkroot and storm.zkroot. Then I provided the whole path to kafak and storm as follows (in application.conf)

capillary.zookeepers="192.168.51.98:2181"
capillary.kafka.zkroot="192.168.50.124:/home/kafka_2.10-0.8.1"
capillary.storm.zkroot="192.168.50.247:/home/storm-0.9.0.1"

Then I started the Capillary again. But I am getting the following exception in terminal where capillary is running

But as the above comment states . I am also having the same issue.

Hey @hsitaa,

Can you show us some of the results from your zkClient.sh regarding the paths above that are reporting null? Also, are you using the version currently in master?

This is mostly likely a configuration issue. Unless you can provide some help there we can't easily help you.
