Stas Levin created STORM-770:
--------------------------------
Summary: NullPointerException in consumeBatchToCursor
Key: STORM-770
URL: https://issues.apache.org/jira/browse/STORM-770
Project: Apache Storm
Issue Type: Bug
Affects Versions: 0.9.2-incubating
Reporter: Stas Levin
We got the following exception after our topology had been up for ~2 days, and
I was wondering if it might be related.
Looks like "task" in "mk-transfer-fn" is null, making "(.add remote
(TaskMessage. task (.serialize serializer tuple)))" fail on NPE
(worker.clj:128, storm-core-0.9.2-incubating.jar)
