Thank you for checking and entering an issue on Github. Would you have any suggestions for us on how to roll back in the most seamless manner?

Thank you for getting back, we are running Cygnus version 0.11.0, which should be the latest on CentOS release 6.6 (Final), which is part of the Orion Context Broker image that runs on the FIWARE lab, that should be version 4.4. I'll follow your comment and use Stackoverflow next time :-)

Hello,

We are experiencing an error in cygnus when trying to persist data to cosmos. We tried to create directories directly with an http request ourselves and that worked fine. I am not sure what kind of information you might need to help, but this is the error message we get in the logs:

2015-12-10 02:40:19 +0100 asked a question ClassNotFoundException in shared hadoop, when trying to create a directory

Hi we are trying to connect a lab node with orion context broker installed to the Cosmos Big Data store. Unfortunately we are experiencing some issues with regards to Cosmos. When trying to create a directory, as explained in the documentation, we are getting the following error message:

[developer@cosmosmaster-gi ~]$ hadoop fs -mkdir /user/developer/testdirectory Java HotSpot(TM) 64-Bit Server VM warning: Insufficient space for shared memory file: /tmp/hsperfdatadeveloper/28027 Try using the -Djava.io.tmpdir= option to select an alternate temp location.

Exception in thread "main" java.lang.NoClassDefFoundError: /tmp/hsperfdatadeveloper/28039 Caused by: java.lang.ClassNotFoundException: .tmp.hsperfdatadeveloper.28039 at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) Could not find the main class: _/tmp/hsperfdata_developer/28039. Program will exit.

Any suggestions?
