Liwei Lin updated SPARK-12305:
------------------------------
Description:
Spark 1.5 has added better Receiver scheduling support, via which users can
deploy Receivers to certain Executors in a way they wish.
However, neither 'Receiver.preferredLocations' info nor the candidate Executors
info are displayed on the web UI. Then when Receivers are not scheduled in the
way users have specified, it's non-trivial for the users to find out why.
This issue proposes to add Receiver scheduling info, including
'Receiver.preferredLocations' info as well as the candidate Executors info,
onto Spark Streaming web UI.
