Hi Danula,
As the pencil down date is tomorrow, shall we have a final demo on the
project after that?
Glad if you can set up the meeting anytime between 5am - 8am OR after 8pm
*EST*.
Thanks,

Hi Nirmal,
I have changed the structure so that operations could be recorded at one
point using the javascript and then executed later by executing a method in
Wrangler class.
public void test(JavaRDDString[] data,String scriptPath)
public JavaRDDString[] executeOperations(JavaSparkContext

Hi Supun,
Following points were discussed in the meeting
*Integration to ML*
We decided to add the wrangler interface as the first step considering the
current ML implementation.
So the steps from a users perspective would be as follows

In ML, what is the preferred way of keeping data in a single row of JavaRDD?
As I have figured it depends on the algorithm being used.

Update on the current progress of the project and future activities as we
discussed at the recent meeting.
*Current Progress*
I have completed the phase of creating spark transformations relevant to
operations available in wrangler.
Operations implemented
- Fill
- Split
- Drop
- Delete
Can you arrange a time around this week? Please check with Nirmal too.

Thanks for the update, keep them coming.
On a JavaRDD you can perform a collect() to get a list, AFAIR. Yes, this is
costly, since it would load whole dataset into memory. So, is this an
operation which involves multiple rows?
