Colin Patrick McCabe updated HADOOP-8742:
-----------------------------------------
Description:
Maven supports compiling software with a different {{javac}} than the one under
the current {{JAVA_HOME}}. See
http://maven.apache.org/plugins/maven-compiler-plugin/examples/compile-using-different-jdk.html
for details.
Although we have never supported this in the past, in the future we could
support compiling the native code with a JDK other than the one referenced by
the JDK in use by Maven. Probably we would add a system property that could be
passed in on the command-line. Perhaps {{-Dnative.jdk.path=...}}.
Another thing to keep in mind is that the native build currently considers
certain properties of the current Java environment when building. For example,
the native build checks {{sun.arch.data.model}} to see if it should build a
32-bit or 64-bit native build. We would have to make sure that this worked
correctly with any "separate native JDK" feature we added.
