Colin Patrick McCabe commented on HADOOP-8887:
----------------------------------------------
So, the two issues from the plugin I saw were this deprecation warning:
{code}
[WARNING]
/testptch/hadoop/hadoop-maven-plugins/src/main/java/org/apache/hadoop/maven/plugin/cmakebuilder/TestMojo.java:[207,30]
[deprecation] getExecutionProperties() in MavenSession has been deprecated
[WARNING]
/testptch/hadoop/hadoop-maven-plugins/src/main/java/org/apache/hadoop/maven/plugin/cmakebuilder/TestMojo.java:[225,29]
[deprecation] getExecutionProperties() in MavenSession has been deprecated
{code}
and a complaint about the use of a hard tab in {{TestMojo.java}}. I opened
HADOOP-12712 to fix these warnings.
Aside from that, we have the usual Jenkins weirdness on one of the test runs.
{code}
java.lang.RuntimeException: Error while running command to get file permissions
: ExitCodeException exitCode=127: /bin/ls: error while loading shared
libraries: libdl.so.2: failed to map segment from shared object: Permission
denied
{code}
{{libdl.so.2}} is a Linux system library-- nothing to do with anything in this
patch. Best guess is that someone ran "apt-get update" concurrently with
Jenkins and hosed this particular unit test.
Does that cover all the issues?

> Currently, we build the native code using ant-build invocations. Although
> this works, it has some limitations:
> * compiler warning messages are hidden, which can cause people to check in
> code with warnings unintentionally
> * there is no framework for running native unit tests; instead, we use ad-hoc
> constructs involving shell scripts
> * the antrun code is very platform specific
> * there is no way to run a specific native unit test
> * it's more or less impossible for scripts like test-patch.sh to separate a
> native test failing from the build itself failing (no files are created) or
> to enumerate which native tests failed.
> Using a native Maven plugin would overcome these limitations.
