My app generates an error message java.lang.ClassNotFoundException: org.littlemonkey.connectivity.NativeConnectivityImpl. at runtime but not at the building process.
I have already imported the org.littlemonkey.connectivity.Connectivity.

When we use spark through zeppelin spark interpreter in share per note model, sometimes we get the following error info:

we have reproduce this error info by the following steps:
create two notes, one is note A, the other is note B
for note A and B, run some paragraghs and see all succeeded
now, delete note A and then we run next paragragh in B, then the error happened
How can we solve this problem? is this a issue of zeppelin spark interpreter itself?
I have run into the same error message. From your description above I realized that I was running two Zeppelin instances with the same interpreter which were pointing to the same data sources (but different notebooks). On my side, I solved the issue by closing the second Zeppelin instance, and restarting my interpret.
I would suggest that you investigate the configs of your interpreter, being global or per user, to see if that may not be the cause of the problem.
I'm getting the below issue when I try to open an ARScene in Android release build. I am not using the 'onTrackingUpdated' method at all.

In Debug build it works fine and I'm able to load a 3D model successfully. The issue happens only in Android Release build.
I executed a query in Saiku and tried to export it to Excel. It throws error page.
Below are the error logs :::

Please assist in resolving this.
You need to have the system fonts installed on your box, I'm guessing you're running a headless Linux system?
I have a program in Apache Flink. I tested and ran it on the local machine and every thing works fine. To run the program on a remote cluster, I did necessary changes as mentioned in Apache Flink Official Website.
I did the following changes:
The two points below
ExecutionEnvironment env = ExecutionEnvironment.getExecutionEnvironment();
ExecutionEnvironment env = ExecutionEnvironment.createRemoteEnvironment("taskManagerName",
portNo,paralelismNo);
Fixing the necessary paths to read input files and write outputs.
Generate a thin jar out of the program and put the necessary jar
libraries into a folder besides my project jar file called
myproj.jar.
copying the data and the jar library and myproj.jar into the cluster
and run the following command remotely on the cluster:
java -cp pathToJarLib \\* -jar myproj.jar
But, I get the below error and I don't have any clue to fix the issue. There are no relevant log files which can aid me in fixing this issue.

Your classpath is obviously not complete. Try to submit via bin/flink run myproj.jar. This sets up the classpath correctly.

The same thing works with SonarQube 5.0.1.
Maybe some defensive programming would have been good in Sonar Runner. A NPE does not tell anything meaningful to a user. I suggest that they include an assertion and if there is a problem that a useful exception message is output.
Most likely some sonar property thats expected a directory were defined with something containing "..". Unfortunately, in my tests, sonar expects an absolut path. I had problems in sonar-ant-runner with sonar.sources, sonar.java.binaries and sonar.projectBaseDir properties.
