[jira] [Created] (FLINK-988)
ExtendedManagementProtocol.getAvailableSlots() returns non-serializable
type
Robert Metzger created FLINK-988:
------------------------------------
Summary: ExtendedManagementProtocol.getAvailableSlots() returns non-serializable type
Key: FLINK-988
URL: https://issues.apache.org/jira/browse/FLINK-988
Project: Flink
Issue Type: Bug
Components: JobManager
Affects Versions: 0.6-incubating
Reporter: Robert Metzger
Priority: Minor
I think the [[ExtendedManagementProtocol.getAvailableSlots()]] method is returning an invalid type.
Our RPC service is casing the return type of the RPC invocation to [[IOReadableWritable]]:
https://github.com/apache/incubator-flink/blob/master/stratosphere-runtime/src/main/java/eu/stratosphere/nephele/ipc/RPC.java#L419
This will lead to a ClassCastException at runtime.
The method getAvailableSlots() is not used for any RPC requests (only for local testing, without an actual RPC call).
