suddendust opened a new issue, #10079:
URL: https://github.com/apache/pinot/issues/10079
Applied JSON index on a tags column with the following config (0.9.0):
```
"jsonIndexColumns": [
"tags"
],
```
Ran the query:
`select span_id from spanEventView where JSON_MATCH(tags,
'"$.http.status"=''200''')`
This throws:
```
[
{
"errorCode": 200,
"message": "QueryExecutionError:\njava.lang.IllegalStateException:
Cannot apply JSON_MATCH on column: tags without json index\n\tat
shaded.com.google.common.base.Preconditions.checkState(Preconditions.java:518)\n\tat
org.apache.pinot.core.plan.FilterPlanNode.constructPhysicalOperator(FilterPlanNode.java:225)\n\tat

org.apache.pinot.core.plan.DocIdSetPlanNode.run(DocIdSetPlanNode.java:49)"
}
]
```
There is no JSON index created on this column (even after reloading the
table). This, however, worked after making the datatype as JSON. Looks like a
bug, as the docs say: Note that JSON index can only be applied to STRING/JSON
columns whose values are JSON strings.
