-------------------------------------
Summary: DruidTranquilityController does not fully support Druid
aggregator
Key: NIFI-5188
URL: https://issues.apache.org/jira/browse/NIFI-5188
Project: Apache NiFi
Issue Type: Bug
Reporter: Dongkyu Hwangbo
Currently DruidTranquilityController does not fully support Druid aggregator
because of some code line hard-codeded in
DruidTranquilityController#getAggregatorList.
{code:java}
...
if (aggregator.get("type").equalsIgnoreCase("count")) {
aggregatorList.add(getCountAggregator(aggregator));
} else if (aggregator.get("type").equalsIgnoreCase("doublesum")) {
aggregatorList.add(getDoubleSumAggregator(aggregator));
} else if (aggregator.get("type").equalsIgnoreCase("doublemax")) {
aggregatorList.add(getDoubleMaxAggregator(aggregator));
} else if (aggregator.get("type").equalsIgnoreCase("doublemin")) {
aggregatorList.add(getDoubleMinAggregator(aggregator));
} else if (aggregator.get("type").equalsIgnoreCase("longsum")) {
aggregatorList.add(getLongSumAggregator(aggregator));
} else if (aggregator.get("type").equalsIgnoreCase("longmax")) {
aggregatorList.add(getLongMaxAggregator(aggregator));
} else if (aggregator.get("type").equalsIgnoreCase("longmin")) {
aggregatorList.add(getLongMinAggregator(aggregator));
}
...
{code}
DruidTranquilityController cannot ingest other Druid aggregator not defined in
above like cardinality, hyperUnique, thetaSketch and so on. Full aggregator
list is in [here|http://druid.io/docs/0.9.2/querying/aggregations.html]
