Here's a cloudera hbase formula.

It depends on our own (cloudera) hadoop.

lib/slf4j-log4j12-1.6.1.jar has been removed, since it duplicates the same jar in hadoop, which SLF4J warns about.

In conf/hbase-env.sh:
    $JAVA_HOME has been set to be the output of /usr/libexec/java_home
    "-Djava.security.krb5.realm= -Djava.security.krb.kdc=" has been added to
    $HBASE_OPTS. See http://stackoverflow.com/q/7134723/580412

In conf/hbase-site.xml:
    hbase.zookeeper.quorum has been set to localhost
    hbase.rootdir has been set to hdfs://localhost:8020/hbase
    hbase.cluster.distributed has been set to true
    dfs.support.append has been set to true
    dfs.client.read.shortcircuit has been set to true

In conf/log4j.properties:
    The level of util.NativeCodeLoader has been set to error.  This merely suppresses an annoying (and unfixable) warning on every run.

launchd scripts have been added for the master, regionserver and zookeeper processes.
