Subject [jira] [Commented] (HADOOP-14088) Java 8 javadoc errors when releasing
Date Fri, 17 Feb 2017 10:43:41 GMT

Steve Loughran commented on HADOOP-14088:
-----------------------------------------

The patches are all done for Hadoop 2.7+, but not branch 2.6

bear in mind that Hadoop 2.6 doesn't, AFAIK, work properly on java 8; Kerberos related.

my recommendation is build/release on java 6 or 7, or go {{-Dmaven.javadoc.skip=true}}

looking at BUILDING.TXT, we don't mention that standard switch...we  ought to

> There are many javadoc errors popping up when releasing Hadoop. After doing some modifications
I have executed the following command to create a release:
> mvn package -pdist -Psrc - Dtar -DskipTests
> Many error regarding the usage of the self-closed tags (like <p/>). Some related
to embedding <ul> into <p> (which seems to be invalid). Many HTML errors (unxesting
tags, etc), problems related with generic representations in javadoc which are being treated
like tags, etc. Unfortunately I cannot contribute my code since I have done some breaking
changes, but I could checkout again and try to fix errors (took me around 8 hours). There
are also loads of warnings, but at least those do not block release.
