[jira] [Commented] (SPARK-25691) Analyzer rule "AliasViewChild"
does not stabilize
[ https://issues.apache.org/jira/browse/SPARK-25691?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16649035#comment-16649035 ]
Marco Gaido commented on SPARK-25691:
-------------------------------------
I think this is actually an instance of a bigger problem, that is we don't always compare properly attributes, ie. we don't always use semantic equality and this may cause bad behaviors (eg. two attributes considered different only for the case while we should be case insensitive and so on). I am going to submit a PR for this. I'll reference this ticket despite I think the scope is bigger. Let me know if you prefer me to open a different one instead. Thanks.
