Nigel Daley resolved HADOOP-2319.
---------------------------------
Resolution: Won't Fix
Closing this. There is an acceptible workaround:
export JAVA_HOME=/path/to/32bit/java
ant -Dcompile.native compile
export JAVA_HOME=/path/to/64bit/java
ant -Dcompile.native compile-core-native tar
The first build creates the 32bit libhadoop. The second build creates the
64bit libhadoop and tars it all up.
> Build both 32 and 64 bit native libraries when compiling with a 64 bit JVM

> Key: HADOOP-2319
> URL: https://issues.apache.org/jira/browse/HADOOP-2319
> Project: Hadoop
> Issue Type: Improvement
> Components: build
> Reporter: Nigel Daley
> Priority: Minor
>
> When a 32 bit JVM is used to build Hadoop, the 32 bit native libraries are
> build (providing -Dcompile.native=true is present). Likewise, a 64 bit JVM
> automatically builds a 64 bit native library.
> It would be helpful if a 64 bit JVM built both 32 and 64 bit native libraries.
