Yin Huai created SPARK-3559:
-------------------------------
Summary: appendReadColumnIDs and appendReadColumnNames introduce
unnecessary columns in the lists of needed column ids and column names stored
in hiveConf
Key: SPARK-3559
URL: https://issues.apache.org/jira/browse/SPARK-3559
Project: Spark
Issue Type: Bug
Components: SQL
Reporter: Yin Huai
Priority: Critical
Because we are using the same hiveConf and we are currently using
ColumnProjectionUtils.appendReadColumnIDs
ColumnProjectionUtils.appendReadColumnNames to append needed column ids and
names for a table, lists of needed column ids and names can have unnecessary
columns.
