--------------------------------
Summary: Make InputGate interface extend AutoCloseable
Key: FLINK-11707
URL: https://issues.apache.org/jira/browse/FLINK-11707
Project: Flink
Issue Type: Sub-task
Components: Network
Reporter: zhijiang
Assignee: zhijiang
Fix For: 1.9.0
This is a sub-task for refactoring the interface of {{InputGate}} which would
be created by {{ShuffleService}} future. So it is reasonable to reference with
general InputGate anywhere instead of specific `SingleInputGate`.
To make {{InputGate}} extend {{AutoCloseable}} interface, the {{TaskCanceler}}
could call {{InputGate#close}} instead of
{{SingleInputGate#releaseAllResources}}.
Next we can further remove the reference with {{SingleInputGate}} in {{Task}}
class by refactoring the {{updatePartitionInfo}} into {{NetworkEnvironment}}.
