Druid JVM config

Hi Team,

My unix machine has only 32 gigs of RAM.

What would be optimal JVM config for each of the nodes of Druid?.

I am trying to process the Twitter data and I am getting the below error:

OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000eab00000, 357564416, 0) failed; error='Cannot allocate memory' (errno=12)

How does your current jvm config look like ?

Look at this doc for simple cluster setup https://druid.apache.org/docs/latest/tutorials/cluster.html

Thanks,

Sashi

Also look at https://github.com/apache/incubator-druid/blob/master/docs/content/operations/basic-cluster-tuning.md
