--------------------------------------
Wei, did you run your test on a single node or multi-node installation?
> Community build Apache Hadoop 2.5 fails on Ubuntu 14.04
> -------------------------------------------------------
>
> Key: HADOOP-10988
> URL: https://issues.apache.org/jira/browse/HADOOP-10988
> Project: Hadoop Common
> Issue Type: Bug
> Components: build
> Affects Versions: 2.2.0, 2.5.0, 2.4.1
> Environment: x86_64, Ubuntu 14.04, OpenJDK 7
> hadoop 2.5 tar file from:
> http://apache.mirrors.pair.com/hadoop/common/hadoop-2.5.0/
> Reporter: Amir Sanjar
>
> Executing any mapreduce applications (i.e. PI) using community version of
> hadoop build from http://apache.mirrors.pair.com/hadoop/common/hadoop-2.5.0/
> fails with below error message. Rebuilding from source on an Ubuntu system
> with flags "clean -Pnative" fixes the problem.
> OpenJDK 64-Bit Server VM warning: You have loaded library
> /home/ubuntu/hadoop/hadoop-2.2.0/lib/native/libhadoop.so.1.0.0 which might
> have disabled stack guard. The VM will try to fix the stack guard now.
> It's highly recommended that you fix the library with 'execstack -c
> <libfile>', or link it with '-z noexecstack'.
