It depends on from which user, you are running storm. That user must own
the folders of storm. So, you need not use chmod but chown.

Hi
This happens when there is some code in bolt or spout which throws Null
Pointer Exception. I suggest you to use Debugger in your IDE, to find out
where is this happening. You can try making a Local Cluster and runs it in
IDE to figure it out easily.
It never happens because of Storm, so do not
Hi
I have a bolt (SPLITTER) which receives data from kafkaspout. The SPLITTER
bolt splits the data and emits them into multiple streams to another bolt
(WRANGLER). The Wrangler takes some time for processing some of the data.
So before it can emit the data to another stream, the spout sends the ne

My use case is that I have a json which contains an array. I need to split
that array into multiple jsons and do some computations on them. After
that, results from each json has to be used in further calculation
altogether and come up with the final result.

But how would that solve the syncing problem?

Hi
I am thinking of doing the following.
Spout subscribed to Kafka and get JSONs. Spout emits the JSONs as
individual tuples.
Bolt-A has subscribed to the spout. Bolt-A creates multiple JSONs from a
json and emits them as multiple streams.
Bolt-B receives these streams and do the computation on
15 matches
