Apache Pinot

Hello everyone,

Did anybody try histogram function?

`SELECT HISTOGRAM(value, 0, 200, 10) as hist from metrics` 

 I am getting following error -
“message”: “QueryExecutionError:\norg.apache.pinot.spi.exception.BadQueryRequestException: Unsupported function: histogram not found

I installed pinot using helm on k8s.

Here is the full error message -

```{
    "message": "QueryExecutionError:\norg.apache.pinot.spi.exception.BadQueryRequestException: Unsupported function: histogram not found\n\tat org.apache.pinot.core.operator.transform.function.TransformFunctionFactory.get(TransformFunctionFactory.java:241)\n\tat org.apache.pinot.core.operator.transform.TransformOperator.&lt;init&gt;(TransformOperator.java:67)\n\tat org.apache.pinot.core.plan.TransformPlanNode.run(TransformPlanNode.java:71)\n\tat org.apache.pinot.core.plan.SelectionPlanNode.run(SelectionPlanNode.java:58)",
    "errorCode": 200
  }```


SELECT HISTOGRAM(“value”, 0, 200, 10) as hist from metrics

it should work. I just tried with the quickstart on latest master.

helm3 repo add pinot <https://raw.githubusercontent.com/apache/pinot/master/kubernetes/helm>

helm chart - APP version - 0.2.5

This is the latest chart.
helm3 search repo pinot -l

I uninstalled the helm chart and reinstalled with the helm parameter  “--set image.tag=latest”
