Trevor Robinson updated HADOOP-9320:
------------------------------------
Attachment: HADOOP-9320.patch
Attached a patch that moves the ARM JVM float ABI detection down below the
search for JAVA_JVM_LIBRARY. It also improves the diagnostics a bit by
reporting which library it's examining and positively confirms if it finds a
hard-float JVM.
> 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

> $ java -version
> java version "1.8.0-ea"
> Java(TM) SE Runtime Environment (build 1.8.0-ea-b36e)

>
> 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.
