Mike Drob commented on HBASE-18269:
-----------------------------------
{quote}
+Set the `$JYTHON_HOME` environment variable to pointing to
+the path to `jython.jar` and each additional Jython-related JAR needed for
{quote}
nit: this should probably say a directory containing jython.jar
{code}
-desc.addFamily(HColumnDescriptor("content:"))
...
+cDesc = HColumnDescriptor("content")
+desc.addFamily(cDesc)
{code}
Does this not work as a single line anymore?
{code}
+data = java.lang.String(result.getValue("content", "qual"))
{code}
specify utf8?
haven't tried running any of the new examples, this was visual review only.
hopefully have time this week.

> The documentation describing how to launch Jython + HBase is out of date.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 Then, the actual code example is out of date too: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):
