--------------------------------------
Summary: Using storm.local.hostname causes bolts to not
communicate with each other
Key: STORM-520
URL: https://issues.apache.org/jira/browse/STORM-520
Project: Apache Storm
Issue Type: Bug
Affects Versions: 0.9.2-incubating
Environment: Docker container (Docker > 1.1.2)
Reporter: Daniel Schonfeld
In our setup we run different supervisors as docker container on top of CoreOS.
If I use docker's -h (host) and give the container the same hostname as the
host machine, the bolts are able to register with nimbus correctly, talk to
each other as well as transfer data inside the same container between different
workers located on the same machine.
Utilizing 'storm.local.hostname' instead of using docker's -h option results in
the bolts having a hard time (read: unable to) communicating between workers on
the same machine/container (we only run one container per physical machine
which contains 4 workers + supervisor) and having sporadic success (50/50)
communicating with bolts in different machines.
