---------------------------------------
Summary: Remove deprecated parquet methods usage from
ParquetMetaStatCollector class
Key: DRILL-6620
URL: https://issues.apache.org/jira/browse/DRILL-6620
Project: Apache Drill
Issue Type: Task
Affects Versions: 1.14.0
Reporter: Arina Ielchiieva
After upgrade to parquet lib 1.10 there are many parquet methods that are
marked as deprecated. Need to update Drill code to use newer methods,
especially in
https://github.com/apache/drill/blob/c6549e58859397c88cb1de61b4f6eee52a07ed0c/exec/java-exec/src/main/java/org/apache/drill/exec/store/parquet/stat/ParquetMetaStatCollector.java
Making such changes would require to change the way how we create parquet
statistics from Drill's {{ColumnMetadata}} class. Since currently it only
stores {{PrimitiveType.PrimitiveTypeName}} info, we might need to change
{{ColumnMetadata}} to hold more information to move to new way of creating
stats.

/**
* Returns the typed statistics object based on the passed type parameter
* @param type PrimitiveTypeName type of the column
* @return instance of a typed statistics class
* @deprecated Use {@link #createStats(Type)} instead
*/
@Deprecated
public static Statistics getStatsBasedOnType(PrimitiveTypeName type) {
