Subject [jira] [Created] (HADOOP-9320) Hadoop native build failure on ARM hard-float
Date Wed, 20 Feb 2013 17:55:12 GMT
Trevor Robinson created HADOOP-9320:

             Summary: 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
$ 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

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.
