normalizePartitionSpec(scala.collection.immutable.Map<String,T> partitionSpec,
StructType partCols,
String tblName,
scala.Function2<String,String,Object> resolver)
Normalize the column names in partition specification, w.r.t.

static void |
requireExactMatchedPartitionSpec(String tableName,
scala.collection.immutable.Map<String,String> spec,
scala.collection.Seq<String> partitionColumnNames)
Verify if the input partition spec exactly matches the existing defined partition spec
The columns must be the same but the orders could be different.

partition column named month
, and it's case insensitive, we will normalize monTh
to
month
