SaintBacchus created SPARK-6584:
-----------------------------------
Summary: Provide ExecutorPrefixTaskLocation to support the rdd
which can be aware of partition's executor location.
Key: SPARK-6584
URL: https://issues.apache.org/jira/browse/SPARK-6584
Project: Spark
Issue Type: Sub-task
Affects Versions: 1.4.0
Reporter: SaintBacchus
The function *RDD.getPreferredLocations* can only be set the host awareness
prefer locations.
If some *RDD* wants to be scheduled by executor(such as BlockRDD), spark can do
nothing for this.
So I want to provide *ExecutorPrefixTaskLocation* to support the rdd which can
be aware of partition's executor location. This mechanism can avoid data
transfor in the case of many executor in the same host.
I think it's very useful especially for *SparkStreaming* since the *Receriver*
save data into the *BlockManger* and then become a BlockRDD
