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?

This issue was fixed. The reason was the shared cluster automatically entered in safe mode.
