I did not find any property to change which Parquet Version Spark uses (V1= , V2). Is there anyway to benefit from the Vectorized Reader? Or this is something= like a new implementation to support this version? I would propose so. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscribe@spark.apache.org For additional commands, e-mail: issues-help@spark.apache.org
