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.
