Hi Spark Experts,
Can someone point me to some examples for non-linear (DAG) ML pipelines.
That would be of great help.
Thanks much in advance

Hello Anjaneya, Marco,
Honestly, Iām not aware if the video broadcasting or recording is planned.
Could you go to the meetup page [1] and raise the question there?
Just in case, here is you can find a list of all upcoming Ignite related events

Hi All, I have this problem where in Spark Dataframe is having null columns
for the attributes from JSON that are not present. A clear explanation is
provided below:
*Use case:* Convert the JSON object into dataframe for further usage.
*Case - 1:* Without specifying the schema for JSON:
Thanks all ā couple notes below.
Generally all our partitions are of equal size (ie on a normal day in this
particular case I see 10 equally sized partitions of 2.8 GB). We see the
problem with repartitioning and without ā in this example we are repartitioning
to 10 but we also see the
Hello all,
I am running PySpark Job (v2.0.2) with checkpoint enabled in Mesos cluster
and am using Marathon for orchestration.
When the job is restarted using Marathon, Spark UI is not getting started
at the port specified by Marathon. Instead, it is picking port from the
checkpoint.
Is there a
Did you also increase the size of the heap of the Java app that is starting
Spark?

I am getting Out of Memory error while running connectedComponents job on
graph with around 12000 vertices and 134600 edges.
I am running spark in embedded mode in a standalone Java application and
have tried to increase the memory but it seems that its not taking any

Sounds like an S3 bug. Can you replicate locally with HDFS?
Try using S3a protocol too; there is a jar you can leverage like so:
spark-submit --packages
com.amazonaws:aws-java-sdk:1.7.4,org.apache.hadoop:hadoop-aws:2.7.3
my_spark_program.py
EMR can sometimes be buggy. :/
You could also try
Are you assuming that all partitions are of equal size? Did you try with more
partitions (like repartitioning)? Does the error always happen with the last
(or smaller) file? If you are sending to redshift, why not use the JDBC driver?

Hi,
I'm using spark 2.1.0 on AWS EMR (Yarn) and trying to use a UDF in python as
follows:
from pyspark.sql.functions import col, udf
from pyspark.sql.types import StringType
path = 's3://some/parquet/dir/myfile.parquet'
df = spark.read.load(path)
def _test_udf(useragent):
return
I am examined the code and found lazy val is added recently in 2.2.0

Hi all,
My team has been experiencing a recurring unpredictable bug where only a
partial write to CSV in S3 on one partition of our Dataset is performed. For
example, in a Dataset of 10 partitions written to CSV in S3, we might see 9
of the partitions as 2.8 GB in size, but one of them as 1.6 GB.
