Replace lib/high-scale-lib.jar with equivalent from maven central repository
----------------------------------------------------------------------------

                 Key: CASSANDRA-1888
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-1888
             Project: Cassandra
          Issue Type: Improvement
    Affects Versions: 0.7.0
            Reporter: Stephen Connolly


As part of my effort to get Cassandra published to Maven Central, there are a 
number of libraries which Cassandra depends on but which are not available in 
Maven Central.

Perhaps the most interesting of these is the Public Domain high-scale-lib.jar

The author is an XML build tool hater (and that includes ANT), and the artifact 
itself contains a lot of unusual cruft... .CVS folders, etc. The build process 
uses a build.java, that effectively is a rewrite of Make in java with the 
Makefile embedded in the build.java.

I have rebuilt the artifacts and published them to the Maven Central 
repository. As part of the requirements for publishing to Maven Central are to 
publish a javadoc.jar and a sources.jar with gpg signatures, etc. It was easier 
to take the source code and transform it into a Maven project.  The project is 
hosted at github: http://stephenc.github.com/high-scale-lib

I have published the following versions, all signed with by [email protected] 
PGP key
1.0.0
1.0.1
1.1.0
1.1.1
1.1.2

These should all be equivalent to the releases by Cliff Click, with the only 
exception being 1.1.1.

For 1.1.1 Cliff's original build script did not run the Unit tests correctly, 
one of the unit tests consistently fails even on his build process due to an 
invalid assumption that element ordering is preserved across serialization for 
NonBlockingIdentityHashMap. He fixed the test in 1.1.2, so I back-ported the 
test change. The code however remains as is.

In any case, can we change the version of high-scale-lib.jar in the lib 
directory to the version from maven central
  
http://repo1.maven.org/maven2/com/github/stephenc/high-scale-lib/high-scale-lib/1.1.1/high-scale-lib-1.1.1.jar
[The current version used by Cassandra is 1.1.1]

Or if perhaps even consider upgrading to 1.1.2 [though I can appreciate that 
this could be considered riskier]

My justification for the change is so that I can be sure that consumers of a 
Maven Central distribution of Cassandra will have exactly the same 
dependencies, which have been tested as part of the Cassandra release process, 
and not just the "Stephen's very damn sure they are the same" dependencies ;-)
