use spark sql to convert this nested structure to different relational
tables

Hello all,
I would like to bring to your attention the (long overdue) release of a new
version of TensorFrames. Thank you to all people who have reported some
packaging and installation issues. This release fixes a large number of
performance and stability problems, and brings a few improvements.
I’m having issues when I fire up pyspark on a fresh install.
When I submit the same process via spark-submit it works.
Here’s a dump of the trace:

Hi all, whoever (Sam I think) was going to do some work on doing a template
testing pipeline. I'd love to be involved, I have a current task in my day
job (data engineer) to flesh out our testing how-to / best practices for
Spark jobs and I think I'll be doing something very similar for the next

Hi all,
Because the Spark Streaming direct Kafka consumer maps offsets for a given
Kafka topic and a partition internally while having enable.auto.commit set to
false, how can I retrieve the offset of each made consumer’s poll call using
the offset ranges of an RDD? More precisely, the informat
Still not working. Seems like there's some syntax error.

Hi,
I have a question regarding Spark streaming resiliency and the
documentation is ambiguous :
The documentation says that the default configuration use a replication
factor of 2 for data received but the recommendation is to use write ahead
logs to guarantee data resiliency with receivers.

You can use
-
start_date_test2.holiday.getItem[0]
I would highly suggest you to look at latest documentation -

How could I access the first element of the holiday column?
I tried the following code, but it doesn't work:
start_date_test2.withColumn("diff", datediff(start_date_test2.start_date,
start_date_test2.holiday*[0]*)).show()

Does anyone have a pyspark example of how to calculate the numbers of days
from the nearest holiday based on an array column?
I.e. from this table
+--+---+
|start_date|holiday|
+--+---+
|2017-08-11|[2017-
Well the 3 in this case is the size of the sparse vector. This equates to
the number of features, which for CountVectorizer (I assume that's what
you're using) is also vocab size (number of unique terms).

Should transfer string to Date type when compare.

I have a column of dates (date type), just trying to find the nearest
holiday of the date. Anyone has any idea what went wrong below?
start_date_test = flight3.select("start_date").distinct()
start_date_test.show()
holidays = ['2017-09-01', '2017-10-01']

|start_date|
