Has anyone disabled directory listing in Zeppelin 0.6.0 (or other version) as a part of security measures?
Could you please let me know about the same.
Following "How to disable directory listing for Jetty's WebAppContext?", I've looked up the Apache Zeppelin installation directory, identified the web.xml file and added
<param-name>dirAllowed</param-name>
<param-value>false</param-value>
After restart it looked like that the configuration parameter wasn't picked up. Directory listing was still possible.
For my understanding, according ZEPPELIN-2014 and a commit, a patch of ZeppelinServer.java would be required to make such configuration possible or active.
It will be fixed as of Zeppelin 0.7.3 or 0.8.0.

We are running a Flink(1.9.1) application on AWS-EMR(5.29) using yarn. We are using a common logging adaptor throughout all the components(including the Flink application) in our project and it uses Log4j2.
From the documentation, I see that there are 3 configuration files.
log4j.properties
log4j-yarn-session.properties
log4j-cli.properties
I understand that I will have to modify log4j.properties for the job manager and task manager logs and log4j-cli.properties for the code not included in the cluster code.
Now given this situation,
How do I pass my log4j2.properties?
Do we replace the logging jars in the lib folder with log4j2 jars?
Not a solid solution but this is a workaround. If the log4j.properties file in the /conf folder is deleted, the log4j2 file within the jar that is within the classpath is referred. But be careful when you have multiple jars in the classpath with the log4j2 properties file.
I want to change the version of cxf on Service Mix 7.0.1 where cxf version is 3.1.9 . Because of using Brave tracing that is implemented in 3.1.12 version of cxf.
So Is there a way to change the version of the CXF on Service Mix.
I have deleted manually everything in the system/apache/cxf folder that has 3.1.9 version and add a file with 3.2.5 version. But it is still not working. When I write feature:list all of the cxf dependencies are with 3.1.9 version...
Deleting files from the system folder won't work. It does not scan the system folder for files, but rather uses it as a cache to go looking for specific versions. You don't need to add new versions to system either because it will download them from the central maven repo it they arn't in system.
If it starts up without a data folder, it will install features & versions listed in org.apache.karaf.features.cfg
One would expect to be able to delete the data folder, change the version in org.apache.karaf.features.cfg & start it up, but I tried that and Camel was broken. Unsure why.
I find it easier to deal with it using the management console.
Install the management console by dropping the following xml file into the deploy folder:
<features name="features-murray" xmlns="http://karaf.apache.org/xmlns/features/v1.2.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://karaf.apache.org/xmlns/features/v1.0.0 http://karaf.apache.org/xmlns/features/v1.2.0">
<repository>mvn:io.hawt/hawtio-karaf/1.5.7/xml/features</repository>
<feature name="murray" version="1" install="auto">
<feature>hawtio-offline</feature>
</feature>
</features>
Then point your browser at http://localhost:8181/hawtio and login with SMX/SMX.
From OSGI/Features add the your new feature version with the plus button:
mvn:org.apache.cxf.karaf/apache-cxf/3.1.12/xml/features
It may take some time to install, because it downloads it from the net. I found it bounced me out of the management console also, but after logging back in I could uninstall the old cxf 3.1.9. It again logged me out of the management console, but after logging back in I had Camel active and CXF on 3.1.12.
No testing though - goodness knows what else is broken.
I am trying to install Bugzilla on centos. Everything in the terminal went fine. But when I try to access Bugzilla through my browser, it is returning the error as shown below.
This XML file does not appear to have any style information associated with it.
The document tree is shown below.
<D:error><C:error/><m:human-readable errcode="2">
Could not open the requested SVN filesystem
</m:human-readable></D:error>"
Can any one help me to solve this issue?
Thanks in advance
The above error rises when there is port conflict between SVN and other applications.
We need to configure virtual host inorde3r to avoid port conflict between svn and other applications.
I have been trying to install Ushahidi platform for weeks but without any luck. I recently started over using Ushahidi latest release ushahidi-Ushahidi_Web-2.0.1-140-g0991172.zip and extracted it to folder ushahidi under my root.
I am using godaddy Linux server. I have tried both the manual and wizard to setup Ushahidi. In all cases, after installation, I get the same error when I try to access admin page. The error reads:
No input file specified.
I have tried tried installing using the wizard and the manual process. My PHP version is as required.
Any help will be appreciated. I need it to work so I can move on and customize it. Very disappointing such a good open source tool has poor installation guides!
Thanks.

there are a few things that can trip up following the installation.
Make sure that:
mod_rewrite is turned on in apache "a2enmod rewrite"
AllowOverride All is set in your apache config for your site (/etc/apache2/sites-available/default)
your .htaccess file points to the correct webroot
I know how to configure solr.home by using Tomcat 6, but I don't know how to set solr.home by using Glassfish(V2.1). I have tried to set the solr.home in .profile as fellows:
export solr.home=/home/huenzhao/search/solr
export solr/home=/home/huenzhao/search/solr
export solr.solr.home=/home/huenzhao/search/solr
export JAVA_OPTS=$JAVA_OPTS -Dsolr.solr.home=/home/huenzhao/search/solr
and they all not work. The error is:
HTTP Status 500 - Severe errors in solr configuration. Check your log
files for more detailed information on what may be wrong. If you want
solr to continue after configuration errors, change:
false in null

Anybody knows?
if you are running solr inside tomcat as a container you can specify the solr home inside the XML descriptor for this webapp. (my terminology for this is probably a little off).
I've got xml fragments for each solr instance I want to run and they specify their own local solr home directory inside the xml fragment. The fragments live at /conf/Catalina/localhost and each one manages a solr instance. This way I can have multiple solr instances on the same machine each with their own solr home variable.
The info is here:
http://wiki.apache.org/solr/SolrTomcat
In paticular
Create a Tomcat Context fragment to
point docBase to the
$SOLR_HOME/apache-solr-1.3.0.war file
and solr/home to $SOLR_HOME:
Symlink
or place the file in
$CATALINA_HOME/conf/Catalina/localhost/solr-example.xml,
where Tomcat will automatically pick
it up. Tomcat deletes the file on
undeploy (which happens automatically
if the configuration is invalid).
Try to set the following:
export JAVA_OPTS="$JAVA_OPTS -Dsolr.solr.home=/home/huenzhao/search/solr/"
Try setting a Java environment parameter from Java or edit your VM configuration:
System.setProperty("solr.solr.home", "/home/user/apache-solr-1.4/example/solr");
In my case I simply copied the 'solr' folder to glassfish/domains/domain1/config and it worked.
