[jira] [Commented] (HADOOP-11875) [JDK9] Renaming _ as a one-character identifier to another identifier

    [ https://issues.apache.org/jira/browse/HADOOP-11875?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15852695#comment-15852695 ] 

Akira Ajisaka commented on HADOOP-11875:
----------------------------------------

New YARN Web UI v2 is now available in Hadoop 3 alpha but I'm thinking the old UI with Hamlet cannot be removed for some time for compatibility and usability. Now I'd like to replace '\_' with '\_\_' for upcoming Java9.

> From JDK9, _ as a one-character identifier is banned. Currently Web UI uses it. We should fix them to compile with JDK9. https://bugs.openjdk.java.net/browse/JDK-8061549
