When this JIRA was opened in 2015 the parquet did not support null types. I commented on this JIRA in May that - given parquet now does include that support - can this bug be reopened ? There was no response. What is the correct way to request consideration of re-opening this issue?

I'd probably suggest they case null to a type CAST(NULL AS INT) if they really want to do this, but really you should just omit the column probably. <https://issues.apache.org/jira/browse/SPARK-10943#> Permalink <https://issues.apache.org/jira/browse/SPARK-10943?focusedCommentId=16462244&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16462244> [image: wabu]Daniel Davis <https://issues.apache.org/jira/secure/ViewProfile.jspa?name=wabu> added a comment - 03/May/18 10:14 According to parquet data types https://github.com/apache/parquet-format/blob/master/LogicalTypes.md, now a Null type should be supported. So perhaps this issue should be reconsidered? <https://issues.apache.org/jira/browse/SPARK-10943#> Permalink <https://issues.apache.org/jira/browse/SPARK-10943?focusedCommentId=16462797&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16462797> [image: javadba]Stephen Boesch <https://issues.apache.org/jira/secure/ViewProfile.jspa?name=javadba> added a comment - 03/May/18 17:08 Given the comment by Daniel Davis can this issue be reopened?
