Hi Hemant - Well it is pretty clear to me that conceptually the
transformations would behave in similar way.
My question is how to identify the parent dependencies as you would
typically do with RDD.
Thanks,
Faiz

Same concept applies to Dataframe as it is with RDD with respect to
transformations. Both are distributed data set.
Thanks

Hello Team,
With RDDs it is pretty clear which operations would result in wide
transformations and there are also options available to find out parent
dependencies
I have been struggling to do the same with DataFrame/DataSet, I need your
helping in finding out which operations may lead to wide
I am confused since the two column have the same name.

Probably it is wrong to compare StringType and ShortType.
I'll use something like this
df.select(colString, colShort,
colShort.equalTo(colString.cast(DecimalType(38,15.show

Run an "explain" instead of show, i'm betting it's casting tier_id to a
small_int to do the comparison

Hello guys,
I am migrating from Spark 1.6 to 2.2 and have this issue:
I am casting string to short and comparing them with equal .
Original code is:
... when(col(fieldName).equalTo(castedValueCol), castedValueCol).
otherwise(defaultErrorValueCol)
Reproduce (version 2.3.0.cloudera4):
scala> val
Thanks Ryan
