lgo opened a new issue #5899:
URL: https://github.com/apache/incubator-pinot/issues/5899
Just a usability thing: when writing out some configuration, there was a
typo in a schema's field name so the star tree configuration did not have a
list of all valid columns. It took a bit of poking to eventually realize the
mistake. For example:
schema
```json
{
"schemaName": "testdata",
"dimensionFieldSpecs": [{
"name": "transaction_id",
"dataType": "STRING"
}],
"metricFieldSpecs": [{
"name": "amount",
"dataType": "DOUBLE"
}],
"dateTimeFieldSpecs": [{
"name": "created_at",
"dataType": "LONG",
"format": "1:SECONDS:EPOCH",
"granularity": "15:MINUTES"
}]
}
```
table
```json
{
"tableName": "testdata",
"tableType": "OFFLINE",
"routing": {
"segmentPrunerType": "partition"
},
"segmentsConfig": {
"timeColumnName": "created_at",
"timeType": "SECONDS",
"replication": "1",
"schemaName": "testdata",
"segmentPushFrequency": "HOURLY",
"segmentPushType": "APPEND"
},
"tableIndexConfig": {
"loadMode": "MMAP",
"starTreeIndexConfigs": [{
"dimensionsSplitOrder": [
"does_not_exist"
],
"functionColumnPairs": [
"COUNT"
],
"maxLeafRecords": 1
}]
},
"tenants": {},
"metadata": {}
}
```
Using `pinot-admin.sh CreateSegment`, this is the exception
```
