Specifying Index Parameters Using the CLI

To specify the parameters for the writers rather than using the default values, you can use the following syntax in the Indexing Configuration file, located at $METRON_HOME/config/zookeeper/indexing.

Create the Indexing Configuration file at $METRON_HOME/config/zookeeper/indexing.
```
touch /$METRON_HOME/config/zookeeper/indexing/index.json
```
Populate the $sensor_name.json file with index configuration information for each of your sensors, using syntax similar to the following:
```
{
   "elasticsearch": {
      "index": "foo",
      "batchSize" : 100,
      "enabled" : true 
    },
   "hdfs": {
      "index": "foo",
      "batchSize": 1,
      "enabled" : true
    }
}
```
This syntax specifies the following parameter values:
- Elasticsearch writer or index
  - index name of "foo"
  - batch size of 100
  - enabled
- HDFS writer or index
  - index name of "foo"
  - batch size of 1
  - enabled

Push the configuration to ZooKeeper:

 /usr/metron/$METRON_VERSION/bin/zk_load_configs.sh --mode PUSH -i /usr/metron/$METRON_VERSION/config/zookeeper -z $ZOOKEEPER_HOST:2181
