[jira] [Commented] (HIVE-7044) ORC Vector: column of empty strings is read back as null

    [ https://issues.apache.org/jira/browse/HIVE-7044?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16900574#comment-16900574 ] 

Hui An commented on HIVE-7044:
------------------------------

Looks like this bug has already fixed in branch-3.1, but I do think we should add this test file to the project.

> If I write a column of empty string values, the vectorized read code returns a vector of nulls, but the non-vectorized code returns the correct values.
