------------------------------------
Summary: Solr for Audit setup doesn't require DocValues
Key: RANGER-1938
URL: https://issues.apache.org/jira/browse/RANGER-1938
Project: Ranger
Issue Type: Bug
Components: audit
Affects Versions: 0.7.1, 0.6.3, 0.6.2, 0.6.1, 0.7.0, 0.6.0
Reporter: Kevin Risden
Ranger uses Ambari Infra Solr (or another Apache Solr install) for storing
Ranger Audit events for displaying in Ranger Admin. In our case, we have
noticed quite a few Ambari Infra Solr OOM due to Ranger. I've talked with a few
other people who are having very similar problems with OOM errors.
I've typed up some details about how the way Ranger is using Solr requires a
lot of heap. I've also outlined the fix for this which significantly reduced
the amount of heap memory required. I'm an Apache Lucene/Solr committer so this
optimization/usage might not be immediately obvious to those using Solr
especially version 5.x.
