Looks like there might be a problem with the way you specified your
parameter values, probably you have an integer value where it should be a
floating-point. Double check that and if there is still a problem please
share the rest of your code so we can see how you defined "gridS".

Can you explain how your initial state is stored? is it a file, or its in a
database?
If its in a database, then when initialize the GroupState, you can fetch it
from the database.

Hi All,
Does rdd.collect() call works for Client mode but not for cluster mode? If
so, is there way for the Application to know which mode it is running in?
It looks like for cluster mode we don't need to call rdd.collect() instead
we can just call rdd.first() or whatever
Thanks!
Thanks Stephen! I appreciate it very much.
And yeah...Stephen is right on this. Go and read the notes and let me know
where you're missing things :-)
p.s. Holden has just announced that her book is complete and think Matei is
also quite far with his writing.

Hi Nipun,
To expand a bit, you might find this stackoverflow answer useful:

Most spark + database combinations can handle a use case like this.
Hope this helps,

Hi all,
With Spark Structured Streaming, is there a possibility to set an "initial
state" for a query?
Using a join between a streaming Dataset and a static Dataset does not
support full joins.
Using mapGroupsWithState to create a GroupState does not support an
initialState (as the Spark
I have this ORC file that was generated by a Spark 1.6 program. It opens
fine in Spark 1.6 with 6GB of driver memory, and probably less.
However, when I try to open the same file in Spark 2.0 or 2.1, I get GC
timeout exceptions. And this is with 6, 8, and even 10GB of driver memory.

Hi everybody.
I'm totally new in Spark and I wanna know one stuff that I do not manage to
find. I have a full ambary install with hbase, Hadoop and spark. My code
reads and writes in hdfs via hbase. Thus, as I understood, all data stored
are in bytes format in hdfs. Now, I know that it's possible
We have the weighting algorithms implemented in linear models, but
unfortunately, it's not implemented in tree models. It's an important
feature, and welcome for PR! Thanks.

Hello,
So, I assume there is nothing to apply/transform in structured streaming based
on a function that takes a dataframe as input and output a dataframe as input?
UDAF are kind of low level and require you to implement merge, and process
individual rows in AFAIK (and are not available in
