Subject [jira] [Commented] (HADOOP-11377) jdiff failing on java 7 and java 8, "Null.java" not found
Date Tue, 24 Mar 2015 05:00:53 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-11377?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14377290#comment-14377290
] 

Tsuyoshi Ozawa commented on HADOOP-11377:
-----------------------------------------

[~vinodkv] To reproduce the problem, please run following command:
{code}
mvn package -Pdocs -DskipTests 
{code}

If FINDBUGS_HOME is set, the command succeeds but the error still occurs because Null.java
is not found - please grep the outputs. The patch fixes the error.

Akira told me that the reason of the build failure is because env.FINDBUGS_HOME is not set.
The ant script cannot find default.xls and fails as a result. We should describe FINDBUGS_HOME
need to be set on  HADOOP-11457. However, I think this problem is not critical issue, so marking
this issue as non-blocker ticket.
