[jira] [Commented] (HIVE-3630) udf_substr.q fails when using JDK7

    [ https://issues.apache.org/jira/browse/HIVE-3630?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13544874#comment-13544874 ] 

Ashutosh Chauhan commented on HIVE-3630:
----------------------------------------

Chris,
I think underlying problem is HIVE-3840. Once we fix that (via which null binary columns will be printed as NULL instead of null) this problem should go away. Right ?

> Internal error: Cannot find ConstantObjectInspector for BINARY
> This exception has two causes.
> JDK7 iterators do not return values in the same order as JDK6, which selects a different implementation of this UDF when the first argument is null. With JDK7 this happens to be the binary version.
> The binary version is not implemented properly which ultimately causes the exception when the method is called.
