--------------------------------
Summary: Dup Execution due to Topology Error
Key: STORM-2433
URL: https://issues.apache.org/jira/browse/STORM-2433
Project: Apache Storm
Issue Type: Bug
Reporter: Qili Chen
We are using storm 1.0.1, at times we get below errors in the topology after
topology running for a long time (e.g. 20 days), which resulting dup
executions. Seems to be some race condition. Could someone help out?
