Steve Loughran commented on HADOOP-3822:
----------------------------------------
I don't know about the impact of Java annotations and javadocs. You can put the
attribute into the java .class files itself, then run code over it, but javadoc
itself doesn't seem to. There are custom javadoc tags, but they are separate
things. If all that is needed is a javadoc tag, then a custom tag like
@hadoop.internal could be added.
> Create a public scheduler API

> The work in HADOOP-3412 provided an API to support pluggable schedulers.
> However implementations have to be in the org.apache.hadoop.mapred package,
> which is undesirable. The goal of this issue is to create a public API for
> scheduler writers to code against.
