I’m all for adding any needed support for java 7 and making Hadoop 2 the default but do they also have to be required?

Unless there is some strong reason it seems like we should support both of those for at least one release, shouldn’t we? I have a hadoop 1.2.1 cluster, which has a hadoop job that is not Hadoop 2 compatible so I’m stuck there for the time being. Compiling Mahout for this now gives an error over the H2 API “isDirectory”, which I think used to be “isDir” for H1. Has that API been deprecated in H2? Are we forced to chose either/or?
