SUCCESS: Integrated in HBase-TRUNK-on-Hadoop-2.0.0 #841 (See

HBASE-8438 Extend bin/hbase to print a "mapreduce classpath"
$ ./bin/hbase mapredcp --help
Usage: hbase mapredcp [-Dtmpjars=...]
Construct a CLASSPATH containing dependency jars required to run a mapreduce
job. By default, includes any jars detected by TableMapReduceUtils. Provide
additional entries by specifying a comma-separated list in tmpjars.
$ ./bin/hbase mapredcp | tr ':' '\n'

> For tools like pig and hive, blindly appending the full output of `bin/hbase
> classpath` to their own CLASSPATH is excessive. They already build CLASSPATH
> entries for hadoop. All they need from us is the delta entries, the
> dependencies we require w/o hadoop and all of it's transitive deps. This is
> also a kindness for Windows, where there's a shorter limit on the length of
> commandline arguments.
> See also HIVE-2055 for additional discussion.
