May be you can repartition?

I think spark.yarn.am.port is not used any more, so you don't need to
consider this.
If you're running Spark on YARN, I think some YARN RM port to submit
applications should also be reachable via firewall, as well as HDFS port to
upload resources.
Also in the Spark side, executors will be
Hi,
I am getting java.lang.OutOfMemoryError: Java heap space error whenever I
ran the spark sql job.
I came to conclusion issue is because of reading number of files from spark.
I am reading 37 partitions and each partition has around 2000 files with
filesize more than 128 MB 37*2000 files
Hi,
In case we run Spark on Yarn in client mode, we have firewall for
Hadoop cluster,
and the client node is outside firewall, I think I have to open some ports
that Application Master uses.
I think the ports is specified by "spark.yarn.am.port" as document says.
Is there a way to parallelize multiple ML algorithms in Spark. My use case is
something like this:
A) Run multiple machine learning algorithm (Naive Bayes, ANN, Random Forest,
etc.) in parallel.
1) Validate each algorithm using 10-fold cross-validation
B) Feed the output of step A) in second

Hi Aakash,
What I see in the picture seems correct. Spark (pyspark) is reading your F2
cell as a multi-line text. Where are the nulls you're referring to?
You might find the pyspark.sql.functions.regexp_replace
Hi,
I've asked this question on SO [1], but hope to catch more attention
posting here.
I'd like to know how many events were late in a streaming batch in
Structured Streaming. Is there a way to know the number or (better)
what events exactly were late?
Thanks for any help you may offer!

Hi,
I've a dataset where a few rows of the column F as shown below have line
breaks in CSV file.
[image: Inline image 1]
When Spark is reading it, it is coming as below, which is a complete new
line.
[image: Inline image 2]
I want my PySpark 2.1.0 to read it by forcefully avoiding the line
10 matches
