Kenneth Yang updated HADOOP-16249:
----------------------------------
    Description: 
A lots of Flink applications run on Hadoop. Flink will invoke Hadoop caller 
context APIs to set up its caller contexts in HDFS/Yarn, so Hadoop should add 
Flink as one of the users in the LimitedPrivate scope.

 

Considering that there are more and more upstream programs(e.g. HBase, HDFS, 
Hive, MapReduce, Pig, Spark, Flink)that rely on CallerContext, Making it 
public+evolving makes sense.
