Subject [jira] [Commented] (SPARK-20700) InferFiltersFromConstraints stackoverflows for query (v2)
Date Tue, 16 May 2017 22:22:04 GMT

    [ https://issues.apache.org/jira/browse/SPARK-20700?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16013199#comment-16013199
] 

Jiang Xingbo commented on SPARK-20700:
--------------------------------------

In the previous approach we used `aliasMap` to link an `Attribute` to the expression with
potentially the form `f(a, b)`, but we only searched the `expressions` and `children.expressions`
for this, which is not enough when an `Alias` may lies deep in the logical plan. In that case,
we can't generate the valid equivalent constraint classes and thus we fail to prevent the
recursive deductions.

I'll send a PR to fix this later today.
