[jira] [Commented] (HIVE-20030) Fix Java compile errors that show
up in IntelliJ from ConvertJoinMapJoin.java and
AnnotateRunTimeStatsOptimizer.java
[ https://issues.apache.org/jira/browse/HIVE-20030?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16528483#comment-16528483 ]
Sergey Shelukhin commented on HIVE-20030:
-----------------------------------------
Could this be Java version related? IIRC I've seen errors with generics inference when using Java 7 that I don't get with Java 8, although the errors were different.

> For some reason the Java compiler in IntellJ is more strict that the Oracle jdk compiler. Maybe this is something that can be configured away, but as it is simple I propose to make the code more type correct.
