---------------------------------
Summary: Channel initialization does not respect JobGraph channel
types
Key: FLINK-921
URL: https://issues.apache.org/jira/browse/FLINK-921
Project: Flink
Issue Type: Bug
Affects Versions: pre-apache-0.5
Reporter: Ufuk Celebi
Initialization of input and output channels has been moved with
2db78a8dc1a4664f3e384005d7e07bea594b835b from `RuntimeEnvironment` to
`initializeChannels(GateDeploymentDescriptor)` in both InputGate and OutputGate
respectively.
When creating a channel, method `getChannelType()` of the abstract Gate class
is called instead of the respective descriptor method, which should be called:
```
this.channels[i] = new OutputChannel(this, i, id, connectedId,
getChannelType());
```
`getChannelType()` of `Gate` returns `ChannelType.NETWORK`, hence currently all
channels are of type `ChannelType.NETWORK`.
This introduceds runtime lookups of channel receivers in `ChannelManager` as
`ChannelManager.register(Task)` does not add it.
introduces runtime lookups for `IN_MEMORY` chann
