------------------------------------------
Summary: Expose some of the collection classes as DeveloperApi
Key: SPARK-6168
URL: https://issues.apache.org/jira/browse/SPARK-6168
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 1.4.0
Reporter: Mridul Muralidharan
Priority: Minor
It would be very useful to mark some of the collection and util classes we have
as @DeveloperApi or even @Experimental.
For example :
- org.apache.spark.util.BoundedPriorityQueue
- org.apache.spark.util.collection.Utils
Usecases for these are for example to do a treeAggregate and/or treeReduce impl
for common api's within RDD which fail due to limitations of aggregate/reduce
at scale (ref: SPARK-6165).
Ofcourse, they are useful for other things too :-)
