URL: https://issues.apache.org/jira/browse/HADOOP-14900
Project: Hadoop Common
Issue Type: Bug
Components: tools
Affects Versions: 3.0.0-beta1
Reporter: Ray Chiang
Assignee: Ray Chiang
Just to document the issue in case other developers run into this. Compiling trunk with jdk 1.8u05 gives the following errors when compiling:
{noformat}

Based on my testing jdk 1.8u92 doesn't produce this error.
I don't think this issue needs to be fixed in the code, but documenting it in JIRA.
