             Summary: Issue while porting Ambari on PPC64: x86_64 code is 
downloaded and run
                 Key: AMBARI-7275
                 URL: https://issues.apache.org/jira/browse/AMBARI-7275
             Project: Ambari
          Issue Type: Bug
    Affects Versions: 1.6.1
         Environment: RHEL 7 / PPC64
            Reporter: Tony Reix


Hi,
I've started porting Ambari 1.6.1(.1) on different environments (IBM PPC64, IBM 
JVM) and I have several issues.
One of them is, on RHEL 7 / PPC64, that Maven downloads x86_64 nodejs code 
(node v0.10.26 and npm 1.4.3) and tries to run it, though I already have nodejs 
available on my machine (/opt/node/bin/node , version v0.10.29).
Changing pom.xml files to  version v0.10.29 for node did not fix the issue.

Following: 
https://cwiki.apache.org/confluence/display/AMBARI/Ambari+Development , I did :
mvn -B clean install package rpm:rpm -DnewVersion=${AMBARI_VERSION} -DskipTests 
-Dpython.ver="python > 2.6" -Preplaceurl

Traces are:

$ file

.../node: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically 
linked (uses shared libs), for GNU/Linux 2.6.9, not stripped

This MVN/Ambari mechanism needs to be changed so that:
 - it does not download nodejs (node, npm) code if node/npm commands are 
already available (with compatible versions) on my machine
 - it uses compatible versions (as an example: use 0.10.29 if available on the 
machine already and version > 0.10.26 is required)
 - it downloads node.js code for my machine architecture (arch awareness) if it 
is not available on the machine where I want to build Ambari.

For now, I found no work-around for this issue.
