[PR] Add range filtering support for iceberg ingestion (druid)
a2l007 opened a new pull request, #15782:
URL: https://github.com/apache/druid/pull/15782
### Description
Adds a new iceberg ingestion filter of type `range` which can be used to filter on ranges of column values. It supports lower and/or upper bounds with `<` , `<=` , `>` , and `>=`
Example spec:
```
"icebergFilter": {
"type" : "range",
"filterColumn" : "price",
"upper": 50,
"lower": 45,
"lowerOpen": true
"upperOpen": false
},
```
which is equivalent to `45 < price <= 50`
This PR also fixes a dependency related issue which may be encountered while talking to Kerberos secured HDFS warehouses.
#### Release note
Adds a new iceberg ingestion filter of type `range` which can be used to filter on ranges of column values.

Review Comment:
I can refactor this in a separate PR since the other filters also need to start using DruidException

I would think so. I will leave it up to you though if the stricter validation is required

Review Comment:
It could be checked, but are you suggesting that the ingest should fail in that scenario?

Review Comment:
Consider using `DruidException` for these validation checks:
```suggestion
if (filterColumn == null) {
throw InvalidInput.exception("filterColumn cannot be null.");
}
```

nit: should we also add checks to validate if `lowerOpen` is specified if `lower` is null as it doesn't make sense? Ditto for `upperOpen`
