Andreas Muttscheller commented on HADOOP-9320:
----------------------------------------------
This problem still exist with Hadoop 2.8. Unfortunatelly, the patch doesn't
work for this version. I updated the patch to work with Hadoop 2.8:

> Hadoop native build failure on ARM hard-float
> ---------------------------------------------
>
> Key: HADOOP-9320
> URL: https://issues.apache.org/jira/browse/HADOOP-9320
> Project: Hadoop Common
> Issue Type: Bug
> Components: native
> Affects Versions: 2.0.3-alpha
> Environment: $ uname -a
> Linux 3.5.0-1000-highbank #154-Ubuntu SMP Thu Jan 10 09:13:40 UTC 2013 armv7l
> armv7l armv7l GNU/Linux
> $ java -version
> java version "1.8.0-ea"
> Java(TM) SE Runtime Environment (build 1.8.0-ea-b36e)
> Java HotSpot(TM) Client VM (build 25.0-b04, mixed mode)
> Reporter: Trevor Robinson
> Assignee: Trevor Robinson
> Labels: BB2015-05-TBR, build-failure
> Attachments: HADOOP-9320.patch
>
>
> ARM JVM float ABI detection is failing in JNIFlags.cmake because
> JAVA_JVM_LIBRARY is not set at that point. The failure currently causes CMake
> to assume a soft-float JVM. This causes the build to fail with hard-float
> OpenJDK (but don't use that) and [Oracle Java 8 Preview for
> ARM|http://jdk8.java.net/fxarmpreview/]. Hopefully the April update of Oracle
> Java 7 will support hard-float as well.
