azagrebin opened a new pull request #8362: [FLINK-11391] Introduce shuffle master interface
URL: https://github.com/apache/flink/pull/8362
 
 
   ## What is the purpose of the change
   
   This PR introduces ShuffleMaster interface. JobMaster and ExecutionGraph use ShuffleMaster to register resources for produced partition of intermediate results. This is part of the overall effort to make shuffle implementation pluggable.
   
   ## Brief change log
   
     - Introduce ShuffleMaster interface
     - Introduce ProducerShuffleDescriptor to describe producer for ShuffleMaster
     - Introduce PartitionShuffleDescriptor to describe partition for ShuffleMaster
     - Introduce ShuffleDeploymentDescriptor: partition handle produced by ShuffleMaster
        to hand over to task and its local shuffle service
     - Introduce UnknownShuffleDeploymentDescriptor for eager consumer scheduling
        when producer is unknown yet
     - Register produced partitions when execution gets slot
     - Refactor TaskDeploymentDescriptor creation into a TaskDeploymentDescriptorFactory
     - Refactor ResultPartitionDeploymentDescriptor to consist of 
        PartitionShuffleDescriptor and ShuffleDeploymentDescriptor
     - Refactor InputGateDeploymentDescriptor and PartitionInfo to use ShuffleDeploymentDescriptor
        instead of InputChannelDeploymentDescriptor
     - Introduce DefaultShuffleMaster and DefaultShuffleDeploymentDescriptor implementations 
        for existing shuffle service based on Netty communication and local files
     - Refactor SingleInputGate.create and updateInputChannel to determine partition location based on 
        consumer resource id and producer id from DefaultShuffleDeploymentDescriptor
     - Adjust tests
