Re: Spark 2.0.0 performance; potential large Spark core regression

Thanks Michael, we can give your options a try and aim for a 2.0.0 tuned vs 2.0.0 default vs 1.6.2 default comparison, for future reference the defaults in Spark 2 RC2 look to be: sql.shuffle.partitions: 200 Tungsten enabled: true Executor memory: 1 GB (we set to 18 GB) kryo buffer max: 64mb

Re: Spark 2.0.0 performance; potential large Spark core regression

Here are some settings we use for some very large GraphX jobs. These are based on using EC2 c3.8xl workers: .set("spark.sql.shuffle.partitions", "1024") .set("spark.sql.tungsten.enabled", "true") .set("spark.executor.memory", "24g") .set("spark.kryoserializer.buffer.max","1g")

Re: Spark 2.0.0 performance; potential large Spark core regression

Hi Adam, From our experience we've found the default Spark 2.0 configuration to be highly suboptimal. I don't know if this affects your benchmarks, but I would consider running some tests with tuned and alternate configurations. Michael > On Jul 8, 2016, at 8:58 AM, Adam Roberts

Re: Spark 2.0.0 performance; potential large Spark core regression

Hi Michael, the two Spark configuration files aren't very exciting spark-env.sh Same as the template apart from a JAVA_HOME setting spark-defaults.conf spark.io.compression.codec lzf config.py has the Spark home set, is running Spark standalone mode, we run and prep Spark tests only, driver

Spark performance regression test suite

Hello, I've seen a few messages on the mailing list regarding Spark performance concerns, especially regressions from previous versions. It got me thinking that perhaps an automated performance regression suite would be a worthwhile contribution? Is anyone working on this? Do we have a Jira

Re: Spark 2.0.0 performance; potential large Spark core regression

Hi Adam, Do you have your spark confs and your spark-env.sh somewhere where we can see them? If not, can you make them available? Cheers, Michael > On Jul 8, 2016, at 3:17 AM, Adam Roberts wrote: > > Hi, we've been testing the performance of Spark 2.0 compared to

Spark 2.0.0 performance; potential large Spark core regression

Hi, we've been testing the performance of Spark 2.0 compared to previous releases, unfortunately there are no Spark 2.0 compatible versions of HiBench and SparkPerf apart from those I'm working on (see https://github.com/databricks/spark-perf/issues/108) With the Spark 2.0 version of SparkPerf

Hi, sharing what I discovered with PySpark too, corroborates with what Amit notices and also interested in the pipe question: h ttps://mail-archives.apache.org/mod_mbox/spark-dev/201603.mbox/%3c201603291521.u2tflbfo024...@d06av05.portsmouth.uk.ibm.com%3E // Start a thread to feed the process

Hi, Read the doc http://spark.apache.org/docs/latest/spark-standalone.html which seems to be the cluster manager the OP uses. Pozdrawiam, Jacek Laskowski https://medium.com/@jaceklaskowski/ Mastering Apache Spark http://bit.ly/mastering-apache-spark Follow me at
