METRON-1521: JSONMapParser is no longer serializable
## Contributor Comments
Currently the JSONMapParser does not function because an anonymous inner
class (TypeRef) is not serializable.
* Create a new parser by editing
`$METRON_HOME/config/zookeeper/parsers/dummy.json` to have the following
content:
```
{
"parserClassName":"org.apache.metron.parsers.json.JSONMapParser",
"sensorTopic":"dummy",
"fieldTransformations" : [
{ "transformation" : "STELLAR"
,"output" : [ "new_field"]
,"config" : {
"new_field" : "JOIN( [ TO_UPPER(source.type), field ], ',' )"
}
}
]
}
```
* Create the dummy kafka topic via
`/usr/hdp/current/kafka-broker/bin/kafka-topics.sh --zookeeper node1:2181
--create --topic dummy --partitions 1 --replication-factor 1`
* Push the zookeeper configs via `$METRON_HOME/bin/zk_load_configs.sh
--mode PUSH -i $METRON_HOME/config/zookeeper -z node1:2181`
* Start the parser via `$METRON_HOME/bin/start_parser_topology.sh -k
node1:6667 -z node1:2181 -s dummy`
* Create some dummy data by creating a file at `~/dummy.dat` with the
following:
```
{ "field" : "f1", "source.type" : "dummy" }
{ "field" : "f2", "source.type" : "dummy" }
{ "field" : "f3", "source.type" : "dummy" }
{ "field" : "f4", "source.type" : "dummy" }
{ "field" : "f5", "source.type" : "dummy" }
{ "field" : "f6", "source.type" : "dummy" }
{ "field" : "f7", "source.type" : "dummy" }
```
* Send the dummy data in via `cat ~/dummy.dat |
/usr/hdp/current/kafka-broker/bin/kafka-console-producer.sh --broker-list
node1:6667 --topic dummy`
* Ensure the data written to the indices has a field `new_field` that looks
like `DUMMY,${field}`
