[jira] [Commented] (HADOOP-10988) Community build Apache Hadoop 2.5
fails on Ubuntu 14.04
[ https://issues.apache.org/jira/browse/HADOOP-10988?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14357429#comment-14357429 ]
Amir Sanjar commented on HADOOP-10988:
--------------------------------------
As a Ubuntu user and developer, how I could help the apache community to fix this problem? could we add a build option to include/build with native 64 bit libraries, only if it is set. I am sure using 64 libraries would improve performance

> 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'.
