Would it really be backwards-incompatible if we added new levels later?
That seems counter-intuitive and contrary to this piece of documentation:
http://docs.oracle.com/javase/specs/jls/se7/html/jls-13.html#jls-13.5.7
Quoting:
Annotation types behave exactly like any other interface. Adding or
removing an element from an annotation type is analogous to adding or
removing a method. There are important considerations governing other
changes to annotation types, but these have no effect on the linkage of
binaries by the Java Virtual Machine. Rather, such changes affect the
behavior of reflective APIs that manipulate annotations. The documentation
of these APIs specifies their behavior when various changes are made to the
underlying annotation types.
Adding or removing annotations has no effect on the correct linkage of the
binary representations of programs in the Java programming language.
Certainly removing existing levels would be backwards-incompatible.

IIRC, it was marked as evolving because it wasn’t clear at the
time whether we would need to add more stability levels. (One of the key
inspirations for the stability levels—Sun’s ARC process—had more.)
So I think it’s important to remember that if this gets changed
to
stable, that effectively means it new levels can’t really get added...

Though it is kinda funny that the InterfaceStability annotation was
marked
as Evolving :)

Hey guys,
I've noticed the InterfaceStability (

)
and InterfaceAudience (
https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-annotations/src/main/java/org/apache/hadoop/classification/InterfaceAudience.java

classes are marked as Evolving. These really haven't changed much
in
the
last few years, so I was wondering if it is reasonable to mark them
as
stable?

Re: InterfaceStability and InterfaceAudience stability
Patch attached. I'm not sure what is necessary for changing the stability
of class. Please review.

[jira] [Resolved] (HADOOP-10875) Sqoop2: Attach a debugger to miniclusters

Resolution: Won't Fix
Wrong project!
Sqoop2: Attach a debugger to miniclusters
-
Key: HADOOP-10875
URL: https://issues.apache.org/jira/browse/HADOOP-10875
Project: Hadoop Common
Issue Type: Bug
Reporter: Abraham Elmahrek
It would be nice to have a way to attach a debugger to the miniclusters:
http://cargo.codehaus.org/Starting+and+stopping+a+container.
For tomcat, I needed to add the following to TomcatSqoopMiniCluster:
{code}
configuration.setProperty(GeneralPropertySet.JVMARGS,
\-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=5005\);
{code}
There should also be a way to attach a debugger to the Yarn container.
