Maximum executors in EC2 Machine

[KhajaAsmath Mohammed]

Hi,

I am running a spark job in spark EC2 machine whiich has 40 cores. Driver
and executor memory is 16 GB. I am using local[*] but I still get only one
executor(driver). Is there a way to get more executors with this config.

I am not using yarn or mesos in this case. Only one machine which is enough
for our work load but the data is increased.

Thanks,
Asmath

Re: automatically/dinamically renew aws temporary token

[Pol Santamaria]

Hi Carlos!

Take a look at this project, it's 6 years old but the approach is still
valid:

https://github.com/zillow/aws-custom-credential-provider

The credential provider gets called each time an S3 or Glue Catalog is
accessed, and then you can decide whether to use a cached token or renew.

Best,

*Pol Santamaria*

Re: automatically/dinamically renew aws temporary token

[Jörn Franke]

Can’t you attach the cross account permission to the glue job role? Why the 
detour via AssumeRole ?

Assumerole can make sense if you use an AWS IAM user and STS authentication, 
but this would make no sense within AWS for cross-account access as attaching 
the permissions to the Glue job role is more secure (no need for static 
credentials, automatically renew permissions in shorter time without any 
specific configuration in Spark).

Have you checked with AWS support?
