Hi, I am trying to figure out how to write parquet metadata when persisting DataFrames to parquet using Spark (1.4.1)
I could not find a way to change schema name (which seems to be hardcoded to root) and also how to add data to key/value metadata in parquet footer. org.apache.parquet.hadoop.metadata.FileMetaData#getKeyValueMetaData org.apache.parquet.schema.Type#getName thanks
