Hi experts,
Sorry if this is a n00b question or has already been answered...
Am trying to use the data frames API in python to join 2 dataframes
with more than 1 column. The example I've seen in the documentation
only shows a single column - so I tried this:
Example code
import pandas a
Any ideas on this? Any sample code to join 2 data frames on two columns?
Thanks
Ali

a = hc.createDataFrame(A)
print A
b = a.select(a.Firstname[:2])
print b.toPandas()
c = a.select(a.Lastname[2:])
print c.toPandas()
Output:

Friendly reminder on this one. Just wanted to get a confirmation that this
is not by design before I logged a JIRA
Thanks!
