Before upgrade, I already change storm.local.dir: to a new location and remove

However, the HashSet is stored in memory, when the data grows to a very large
level, I think it will cause a OOM.
So is there a scalable solution?

the code is simple, but I don’t have a cluster so I wanna run this topology
with local cluster with a local drpc, but I don’t know how, any idea?

, you lose a worknode in your
cluster. It is always a good practice to run nimbus and supervisor under
monitor application.

everyone, do you have some best practice or pattern for tunning the storm
cluster, like how to set the number of workers, the numbers of spout and bolts,
etc..
Any advice is welcome.

I think you should change the scope of storm-kafka, the storm server only
provides the storm-core.
org.apache.storm
storm-kafka
0.9.2-incubating
compile
