Tom Beerbower commented on AMBARI-8125:
---------------------------------------

If I use jar to look at the contents of the slider view jar on ec2-54-173-87-201.compute-1.amazonaws.com,
I see that it does contain a view.xml ...

{code}
[root@ip-172-31-39-112 ~]# /usr/jdk64/jdk1.7.0_67/bin/jar tvf /var/lib/ambari-server/resources/views/slider-0.0.1-SNAPSHOT.jar
| grep view.xml
  3654 Sun Nov 02 18:17:24 UTC 2014 view.xml
{code}

... but, the DEBUG output shows that the view.xml is never being extracted.

If I grep the logs with the following I should see DEBUG for the slider view.xml file, but
I don't see it.

{code}
grep "Extracting "  /var/log/ambari-server/ambari-server.log* | grep SLIDER{1.0.0} | grep
view.xml
{code}

Locally, with a successfully extracted slider view I see the following result for the above
grep.

{code}
[root@c6401 ~]# grep "Extracting "  /var/log/ambari-server/ambari-server.log* | grep SLIDER{1.0.0}
| grep view.xml
13:42:09,515 DEBUG [pool-1-thread-1] ViewExtractor:98 - Extracting /var/lib/ambari-server/resources/views/work/SLIDER{1.0.0}/view.xml
{code}

Also, if I compare the extracted folder on ec2-54-173-87-201.compute-1.amazonaws.com ...

{code}
[root@ip-172-31-39-112 ~]# ls /var/lib/ambari-server/resources/views/work/SLIDER\{1.0.0\}/
404.html  data  favicon.ico  font  img  javascripts  META-INF  org  slider.properties  stylesheets
 WEB-INF
{code}

to the locally extracted folder ...

{code}
[root@c6401 ~]# ls /var/lib/ambari-server/resources/views/work/SLIDER\{1.0.0\}/
404.html                          crossdomain.xml  favicon.ico  img         javascripts  org
               stylesheets  view.xml
apple-touch-icon-precomposed.png  data             font         index.html  META-INF     slider.properties
 tests.html   WEB-INF
{code}

I see that more than just the view.xml is missing.
