Hi everyone,
I am trying to deploy the storm on AWS cluster, and getting following
error.
I am using a mac machine, so these are the steps I followed:
1. downloaded lein, converted it to executable, moved to usr/local/bin and
executed same.
2. did a git clone of storm deploy code.
3. cd into s
Thanks Taylor. I was afraid creating the JRuby runtime this way might be
expensive. Initially I did create it inside of the prepare() method but I
ran into some trouble because the Ruby class is not serializable. I played
around with it a little more today and I had some success creating a static

I've been working on a proof of concept with Storm and got it working in
Local Mode. I'm running into problems when I try to deploy though. When I
launch Storm UI, I see that all bolts are running on only one of the
workers! I can't for the life of me figure out why. I.e. when I look at

Hi Jonathan,
I've used jruby fairly extensively with storm (though with the trident API),
but it's been a while so I'm rusty.
Initializing the jruby runtime is very expensive, so you should do that in the
prepare() method of your bolt. That means you'll have to store it as an
instance variable
I purposely left out storm-starter from the discussion to keep things focused,
and because it’s a different animal. But I also feel it should be pulled in,
albeit differently. I was thinking something along the lines of an “examples”
directory, and that all committers would share collective

Bobby,
I vote to include both storm-yarn and storm-deploy.

Bobby,
FWIW, I¹d love to see storm-yarn inside. I think we could definitely make
things easier on the end-user if they were more cohesive.
e.g. Imagine if we had ³storm launch yarn² inside of $storm/bin that would
kickoff a storm-yarn launch, with whatever version was built. It would

Thanks for the feedback Bobby.
To clarify, I’m mainly talking about spout/bolt/trident state implementations
that integrate storm with *Technology X*, where *Technology X* is not a
fundamental part of storm.
Examples would be technologies that are part of or related to the Hadoop/Big

Hi,
I'm trying to write some storm bolts and I want them to output the
information they produce into HBase.
Now the HBase we have running here is based on CDH 4.5.0 which is fully
based on the zookeeper versions in the 3.4.x range.
The problem I have is that Storm currently still uses zookeeper 3
In my case it was the state objects created as part of trident aggregation.

Hi Adam,
ok, good to know. I resolved to create the tuple from scratch in case it
needs to be resend. I don't where else in-place modification could hurt
in a linear process. Am I missing something?
Thanks,
Harald.

I've already gotten slapped around on the list for doing in place
modifications, so let me pass it on :)
Don't modify tuple objects in place.
You shouldn't rely on serialization happening or not happening for
correctness.

Ah! I accidentally unpacked source on top of binary, when I meant to put

Hello, Padma!
You can create a storm cluster on Windows with one node as described
here:
http://ptgoetz.github.io/blog/2013/12/18/running-apache-storm-on-windows/
I could set up following the instructions from this article.
I hope that will help you also.

Hi Klaus,
I've been dealing with similar use cases. I do a couple of things (which
may not be a final solution, but it is interesting to discuss alternate
approaches): I have passed trained models in the 200MB range through storm,
but I try to avoid it. The model gets dropped into persistence and
The defaults.yaml file is part of the source distribution and is packaged into
storm's jar when deployed.
In a storm cluster deployment, it is not meant to be on the file system in
${storm.home}/conf.
Perhaps you are pointing to your source working tree as storm home?

Sharding is a pain in the ass and should be avoided when possible.
If its possible, I'd look for another data store that can handle a higher
load as a cluster so you don't have to worry about the details of sharding.

Is your mysql set up to handle 1000 writes a second?
I'm going to guess no. If that is the case then Klaus' suggestions are good
ones. Batch or Shard.

Hi,
if you want to stick to MySQL I see two options:
1) You could try to batch your writes. The DbWriterBolt would buffer some
writes (e.g.) thousand and write them in batch mode. This is usually much
faster. However your database is not always up to date.
2) You could try to shrad you database
There are good basic default configurations for each. There's nothing you
should have to do. Older versions of storm 0.9.x defaulted to ZeroMQ, the
latest defaults to Netty. I would advise not tuning any parameters of
either until you need to and understand what you are doing.

How much traffic exactly are you pushing at mysql before the load gets to
high and it starts to buckle under the weight?

Dear All,
Have any body worked on the configurations/optimizations needed generally
for using STORM with MYSQL. Our scenario stores data in MYSQL tables, but
as the data rate increases MYSQL starts responding very slow (in some cases
connection refused error), resulting in DBWriterBolt to slowdown
Well 6700 isnt running at all. There's no uptime so they aren't ever
starting.
6701 appears to have died 20 minutes before you took the screenshot, that
is going to result in load being shuffled around.
So you had 3 functional workers, 6701, 6702, 6703 and 6701 went down

the idea is good, I will keep that in mind. The only drawback is that it
relies on polling, what I do not like to much in the PredictionBolt. Off

Quick question on this: defaults.yaml is in both conf and
storm-core.jar, so the first time you start nimbus 0.9.1 you get this

You're probably bundling the Storm jars with your topology jar.

I can't comment on how large tuples fare, but about the synchronization,
would this not make more sense?

I have a topology which process events and aggregates them in some form and

Using normal storm, any bolt can output to anything at any time, as each bolt
runs arbitrary code. So a bolt in the middle of a topology can write to a
database, or file, or anything else you need. It will likely be the last bolt
in the topology, but it doesn't have to be.
If you use trident, t

I have released a Puppet module to deploy Storm 0.9 in case anyone is

The module uses Puppet parameterized classes and as such decouples code
