[jira] [Created] (SPARK-7167) Receivers are not distributed efficiently

Marius Soutier created SPARK-7167:
-------------------------------------

             Summary: Receivers are not distributed efficiently
                 Key: SPARK-7167
                 URL: https://issues.apache.org/jira/browse/SPARK-7167
             Project: Spark
          Issue Type: Bug
          Components: Streaming
    Affects Versions: 1.2.2, 1.2.1
            Reporter: Marius Soutier


Bug report: I'm seeing an issue where after starting a streaming application from a checkpoint, the network receivers are distributed such that not all nodes are used.

For example, I have five nodes:
node0 - 1 receiver
node1 - 2 receivers
node2 - 0 receivers
node3 - 2 receivers
node4 - 0 receivers

This slows down the job, waiting batches pile up, and I have to kill and restart it, hoping that next time it will be distributed in a sensible fashion.
