Pavel Smirnov closed STORM-1779.
--------------------------------
Resolution: Fixed
> 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
> Labels: bug, scheduler
>
> I have designed a 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-components topopoly the breadth-first search (bfs method in
> DefaultResourceAwareStrategy.java:323) returns 13 components, which is
> obviously incorrect for further scheduling (it fails on memory limits trying
> to schedule already scheduled tasks in priorityToExecutorMap).
> 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 the 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
