[GitHub] [incubator-pinot] lgo opened a new issue #5899: NullPointerException when star-tree index configuration refers to invalid column

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
   ```
