-----------------------------------
Summary: Streaming checkpoints consider only input and output
vertices
Key: FLINK-2063
URL: https://issues.apache.org/jira/browse/FLINK-2063
Project: Flink
Issue Type: Bug
Components: Streaming
Affects Versions: 0.9
Reporter: Stephan Ewen
Assignee: Stephan Ewen
Fix For: 0.9
Currently, the streaming checkpoint coordinator is configured only with the
list of input and output vertices as stateful vertices.
Checkpoint confirmations from intermediate vertices are ignored.
Since the runtime assumes that all vertices participate in checkpointing
anyways (all of them send acknowledge messages), the coordinator should be
configured accordingly.
