Re: Apache Spark security.NosuchAlgorithm exception on changing from java 7 to java 8

There should be a spark-defaults.conf file somewhere in your machine; that's where the config is. You can try to change it, but if you're using some tool to manage configuration for you, your changes might end up being overwritten, so be careful with that. You can also try "--properties-file

Thank you Marcelo. I don't know how to remove it. Could you please tell me how I can remove that configuration? On Mon, Jun 6, 2016 at 5:04 PM, Marcelo Vanzin wrote: > This sounds like your default Spark configuration has an > "enabledAlgorithms" config in the SSL

Re: Apache Spark security.NosuchAlgorithm exception on changing from java 7 to java 8

This sounds like your default Spark configuration has an "enabledAlgorithms" config in the SSL settings, and that is listing an algorithm name that is not available in jdk8. Either remove that configuration (to use the JDK's default algorithm list), or change it so that it lists algorithms

Thank you Ted for the reference. I am going through it in detail. Thank you Marco for your suggestion. I created a properties file with these two lines spark.driver.extraJavaOptions -Djsse.enableSNIExtension=false spark.executor.extraJavaOptions -Djsse.enableSNIExtension=false and gave this

Please see: https://spark.apache.org/docs/latest/security.html w.r.t. Java 8, probably you need to rebuild 1.5.2 using Java 8. Cheers On Mon, Jun 6, 2016 at 1:19 PM, verylucky...@gmail.com < verylucky...@gmail.com> wrote: > Thank you for your response. > > I have seen this and couple of other

Thank you for your response. I have seen this and couple of other similar ones about java ssl in general. However, I am not sure how it applies to Spark and specifically to my case. This error I mention above occurs when I switch from java 7 to java 8 by changing the env variable JAVA_HOME. The

Apache Spark security.NosuchAlgorithm exception on changing from java 7 to java 8

Hi, I have a cluster (Hortonworks supported system) running Apache spark on 1.5.2 on Java 7, installed by admin. Java 8 is also installed. I don't have admin access to this cluster and would like to run spark (1.5.2 and later versions) on java 8. I come from HPC/MPI background. So I naively
