Review comment:
@viirya Hive tables are converted To `HiveTableScanExec` instead of
`Logical Relation`(which inturn uses HadoopFSRelation) . This happens in
`org.apache.spark.sql.hive.HiveStrategies.HiveTableScans` . It will not affect
HadoopFSRelation I think. Let me know if I am missing some thing
Note: conversion to HiveTableScanExec happen for Hive table with any formats
other than Parquet and Orc.
In case or Orc and Parquet, it happens when the flag to convert to
datasource table is disabled.
