Nick Dimiduk commented on MAPREDUCE-4959:
-----------------------------------------

As I consider this further, I don't think generating a temp jar is sufficient for our needs. What we want is the hbase-manifest.jar to be created a install time, once all of the path structures are resolved.

HBase's current minimum Hadoop version is at 1.1.2. I don't know what the future will hold.

Ping [~apurtell] for thoughts on both points.

> To support long classpaths on Windows, the class path entries get bundled into a small temporary jar with a manifest that has a Class-Path attribute.  When a classpath is specified in a jar manifest like this, it does not expand environment variables (i.e. %HADOOP_COMMON_HOME%), and it does not expand wildcards (i.e. lib/*.jar).
