> The documentation describing how to launch Jython + HBase is out of date. - https://hbase.apache.org/book.html#jython
> First, we would set the classpath differently:
> {noformat}
> HBASE_CLASSPATH=/home/hbase/jython.jar bin/hbase org.python.util.jython
> {noformat}
> Then, the actual code example is out of date too:
> {noformat}
> >>> desc = HTableDescriptor(tablename)
> >>> desc.addFamily(HColumnDescriptor("content:"))
> Traceback (most recent call last):
>   File "<stdin>", line 1, in <module>
> 	at org.apache.hadoop.hbase.HColumnDescriptor.isLegalFamilyName(HColumnDescriptor.java:566)

> We should make sure that the examples we claim are runnable actually are.
