            EMR ignores spark submit parameters (memory/cores/etc)
            Asked 2021-Oct-01 at 21:05

            I'm trying to use all resources on my EMR cluster.

            The cluster itself is 4 m4.4xlarge machines (1 driver and 3 workers) with 16 vCore, 64 GiB memory, EBS Storage:128 GiB

            When launching the cluster through the cli I'm presented with following options (all 3 options were executed within the same data pipeline):

            Just use "maximizeResourceAllocation" without any other spark-submit parameter

            This only gives me 2 executors presented here

            Don't put anything, leave spark-defaults to do their job

            Gives following low-quality executors

            Use AWS's guide on how to configure cluster in EMR

            Following this guide, I deduced following spark-submit parameters:

            Have you tried setting --master yarn parameter and replace parameter spark.executor.memoryOverhead by spark.yarn.executor.memoryOverhead ?

            Use Apache Spark efficiently to push data to elasticsearch
            Asked 2020-Nov-03 at 10:13

            I have 27 million records in an xml file, that I want to push it into elasticsearch index Below is the code snippet written in spark scala, i'l be creating a spark job jar and going to run on AWS EMR

            How can I efficiently use the spark to complete this exercise? Please guide.

            I have a gzipped xml of 12.5 gb which I am loading into spark dataframe. I am new to Spark..(Should I split this gzip file? or spark executors will take care of it?)

            ...

            Not a complete answer but still a bit long for a comment. There are a few tips I would like to suggest.

            It's not clear but I assume your worry hear is the execution time. As suggested in the comments you can improve the performance by adding more nodes/executors to the cluster. If the gzip file is loaded without partitioning in spark, then you should split it to a reasonable size. (Not too small - This will make the processing slow. Not too big - executors will run OOM).

            parquet is a good file format when working with Spark. If you can convert your XML to parquet. It's super compressed and lightweight.

            Reading on your comments, coalesce does not do a full shuffle. The coalesce algorithm changes the number of nodes by moving data from some partitions to existing partitions. This algorithm obviously cannot increase the number of partitions. Use repartition instead. The operation is costly but it can increase the number of partitions. Check this for more facts: https://medium.com/@mrpowers/managing-spark-partitions-with-coalesce-and-repartition-4050c57ad5c4
