Deegue created SPARK-26577:
------------------------------
Summary: Add input optimizer when reading Hive table by SparkSQL
Key: SPARK-26577
URL: https://issues.apache.org/jira/browse/SPARK-26577
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.4.1
Reporter: Deegue
When using SparkSQL, for example the ThriftServer, if we set
`spark.sql.hive.fileInputFormat.enabled=true`
we can optimize the InputFormat to CombineTextInputFormat automatically if it's
TextInputFormat before. And we can also change the max/min size of input splits
by setting, for example
`spark.sql.hive.fileInputFormat.split.maxsize=268435456`
`spark.sql.hive.fileInputFormat.split.minsize=134217728`
Otherwise, we have to modify Hive Configs and structure of tables.
