----------------------------------------

             Summary: LogSearch: Need to decrease mergeFactor to enable purge of documents
more often
                 Key: AMBARI-16110
                 URL: https://issues.apache.org/jira/browse/AMBARI-16110
             Project: Ambari
          Issue Type: Bug
            Reporter: Don Bosco Durai


LogSearch deletes logs older than 7 days (by default). The indexed documents doesn't get purged
until the segments are merged. Currently the mergeFactor is 25, which is pretty large. If
documents are not purged, then the indexes occupy disk and memory. 

It is better to make the mergeFactor value to be 5 and let Solr purge deleted documents more
regularly.

The following 2 files needs to be updated:
ambari-server/src/main/resources/common-services/LOGSEARCH/0.5.0/properties/audit_logs-solrconfig.xml.j2
ambari-server/src/main/resources/common-services/LOGSEARCH/0.5.0/properties/service_logs-solrconfig.xml.j2
