I had the same problem. It may be an error on your part, or may be down to your environment. Either way, try these three things:
Put #layout('master') right at the top of your php file - no white
space.
Make sure your master view is labelled master.blade.php - no
capitals.
Make sure master.blade.php is in application/views
Note: If you have your master view in a different folder e.g. application/views/some_folder the correct way to call it is #layout('some_folder.master')


Use
#extends('master') instead of #layout('master')

Can anyone see what is the issue ? any help or pointer ?

Usually, I have noticed this error when there is an issue with the program. If you have access to the cluster i.e. ssh clsadmin# , you can try running the java program using spark-submit and confirm that the program is valid and there is no issue.

1) Could you please check the Livy log on the spark node (/var/log/livy2) for any error messages logged there?
2) You can also try restarting Livy service on your cluster?
On our test server able to run the sample code:
bx ae spark-submit --className org.apache.spark.examples.SparkPi local:/usr/hdp/current/spark2-client/jars/spark-examples.jar

change layout in different module on zf3

while i change layout in different mudule on zf3, there is a error caused.

i have no idea to solve this problem.
i used the tutorial :

You can check implementation or just use this module

Primefaces tag library on tomcat, rendering an empty page from a valid jsp file

I've posted here earlier about how to make a tic tac toe for two users using jsf and I got the link for this great taglib, Primefaces. It's absolutely perfect for what I need to do, but I'm being stuck on trying to make it do anything, even render the examples from their website.
So I've been following this tutorial I found (sadly, there aren't many of them on the subject of Primefaces): http://java.dzone.com/articles/primefaces-quickstart-tutorial
Step by step, I made everything according to this tutorial, yet when I run it, it renders an empty page every time.
So I tried a simpler example from the official website: http://www.primefaces.org/gettingStarted.html
This (test.xhtml):
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:p="http://primefaces.org/ui">
<h:head>
</h:head>
<h:body>
<p:spinner />
</h:body>
</html>
renders an empty page, while this:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:p="http://primefaces.org/ui">
<h:head>
</h:head>
<h:body>
test test test test
<p:spinner />
</h:body>
</html>
renders only the "test test test test" text.
So I guess the problem must be in the tags, tomcat doesn't see them/doesn't know how to interprete them.
But, according to the tutorial and the primefaces website all I need to do is to put the jars in WEB-INF/lib as I have done (by the way, I'm using Eclipse and the empty project I created was "Dynamic Web Project").
In my WEB-INF/lib I have the following jars:
jsf-api-2.0.3.jar
jsf-impl-2.0.3.jar
jstl-1.0.2.jar
primefaces-3.3.RC1.jar
If it's of any help, here's the content of the tomcat console:
2012-05-27 13:18:11 org.apache.catalina.core.AprLifecycleListener init
INFO: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: .:/Library/Java/Extensions:/System/Library/Java/Extensions:/usr/lib/java

2012-05-27 13:18:17 org.apache.catalina.startup.Catalina start
INFO: Server startup in 5096 ms
What can be the case? Am I putting the jars in wrong place, is it a tomcat failure or maybe something else entirely?

Ok, I solved it, maybe someone will someday find this useful.
So, when using Primefaces with JSF, not only the webpage files have to have the .xhtml extension (a solution I've found here: http://www.coderanch.com/t/473437/JSF/java/not-allowed-template-text), but also the web.xml file must be modified (a solution I've found here: Simple primefaces application not working), like this:
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
Now it works perfectly well.
