-----------------------------------
Summary: Index Appending when Duplicate Column names
Key: SPARK-34992
URL: https://issues.apache.org/jira/browse/SPARK-34992
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 3.1.1
Reporter: Hallah Butt
In reference to below mentioned link
[https://github.com/apache/spark/pull/14745]
I am reporting this issue that can it should be configurable to append values
when we have duplicate columns? For instance, instead of always appending
column index, there should be configurable leverage to append any sort of
string. Lets say, instead of Cola2 and Cola34, we can set as Cola[xyz] and
Cola1.
