Modifying Index Parameters Using Ambari

You can modify various indexing properties using Ambari. The HDFS sync policy is not currently managed by Ambari. To accommodate the HDFS sync policy setting, modify the Flux file directly.

To modify the indexing properties, navigate to Ambari>Metron>Indexing.

The following table lists the indexing properties you can modify in Ambari:

Category Ambari Property Name Storm Property Name
