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.
