If you are seeing precommit failures, like this: [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project hadoop-annotations: Compilation failure [ERROR] javac: invalid flag: -Xmaxwarns=9999 [ERROR] Usage: javac <options> <source files> [ERROR] use -help for a list of possible options
[ERROR] -> [Help 1] it was caused by HADOOP-17661 <https://issues.apache.org/jira/browse/HADOOP-17661>. I have just reverted the commit. (the precommit for the PR didn't fail, so it wasn't caught in the first place) Sorry for the trouble Weichiu
