Pavel Smirnov created STORM-1779:
------------------------------------
Summary: Incorrect bfs-ordering in DefaultResourceAwareStrategy
Key: STORM-1779
URL: https://issues.apache.org/jira/browse/STORM-1779
Project: Apache Storm
Issue Type: Bug
Components: storm-core
Affects Versions: 1.0.0
Reporter: Pavel Smirnov
Priority: Minor
I have designed simple diamond topology:
spout, N parallel processingBolts, joinBolt.
(https://github.com/smirnp/storm-benchmark/blob/1.0.0/src/storm/benchmark/DiamondTopology.java)
For 6-component's topopoly the breadth-first search (bfs method in
DefaultResourceAwareStrategy.java:323) returns 13 components, which is
obviously incorrect for further scheduling.
I have reimplemented bfs with the comparison with the original-one
(https://github.com/smirnp/storm-benchmark/blob/1.0.0/bfs.txt)
Please check it and fix a bug in next releases.
P.S. storm.yaml user for scheduling is here:
https://github.com/smirnp/storm-benchmark/blob/1.0.0/storm.yaml
Best regards,
Thanks
