How to Increase Ranger Admin Heap Size?

hkropp — Thu, 01 Oct 2015 02:10:22 GMT

How can the heap size of the Ranger Admin service be increased? What is a good recommended value?

What is the reason for increasing the heap? Are you seeing OOM errors due to too many users?

You can edit JAVA_OPTS property in below file. You can leave the default 1g. It should work fine.

In HDP 2.2:

/usr/hdp/2.2.x/ranger-admin/ews/start-ranger-admin.sh

In HDP 2.3:

/usr/hdp/2.3.x/ranger-admin/ews/ranger-admin-services.sh

Preferred way is to create a file like ranger-admin-env00-java_mem.sh in /etc/ranger/admin/conf and have the following values:

JAVA_OPTS=" -XX:MaxPermSize=256m -Xmx1024m "

export JAVA_OPTS

In this way, even when Ranger is upgraded, your custom overrides are still there.
