Ufuk Celebi created FLINK-4036: ---------------------------------- Summary: Potential deadlock in StreamIterationSink Key: FLINK-4036 URL: https://issues.apache.org/jira/browse/FLINK-4036 Project: Flink Issue Type: Bug Reporter: Ufuk Celebi Assignee: Ufuk Celebi
When the stream iteration head finishes before the iteration tail acquires the feedback queue, the tail will block indefinitely. This happened here: https://s3.amazonaws.com/archive.travis-ci.org/jobs/134215892/log.txt You can provoke this by adding a sleep before acquiring the feedback queue in {{StreamIterationTail}} and running {{IterateTest.testSimpleIteration}}. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
