----------------------------------
Summary: IOManagerAsync not properly shut down in various tests
Key: FLINK-8145
URL: https://issues.apache.org/jira/browse/FLINK-8145
Project: Flink
Issue Type: Bug
Components: Tests
Affects Versions: 1.4.0
Reporter: Nico Kruber
Assignee: Nico Kruber
In various tests, e.g. {{AsynchronousBufferFileWriterTest}},
{{BufferFileWriterReaderTest}}, or {{HashTableITCase}}, {{IOManagerAsync}}
instances are used which are not shut down at all. The only thing cleaning them
up seems to be a shutdown handler attached to the JVM. Since each
{{IOManagerAsync}} is spawning a number of reader and writer threads, this may
put a significant burden on the tests.
