I think launchd is the answer, but using this plist:
http://gist.github.com/553573
I get this error:
Exception in thread "main" java.lang.NoClassDefFoundError: net/appjet/oui/main
Caused by: java.lang.ClassNotFoundException: net.appjet.oui.main

at java.security.AccessController.doPrivileged(Native Method)
...
Any ideas?
Classpath problems perhaps? The script /usr/local/etherpad/trunk/etherpad/bin/run-local.sh is supposed to be started from a specific directory (path). Try editing your copy to start with a cd command to go the right folder just before it creates subfolders data/appjet.

At the moment I'm trying to run my first flink application. I already tested the java file (KMeans.java) in the IDE and it works perfectly but I can't handle to get this java file run as an jar in command line.
The build was successfully created with mvn clean package.
But if I run my jar file in command line flink run -c KMeans name.jar
this error message appears:
The program finished with the following exception:
org.apache.flink.client.program.ProgramInvocationException: The
program's entry point class 'KMeans' was not found in the jar file.

So I looked up my generated target folder and there is a KMeans.class file in the classes folder. So I'm doing this wrong?
You need to specify the full class name, e.g., org.apache.flink.examples.java.clustering.KMeans.
Note that you only need to use the -c flag if the JAR file doesn't specify the class to run in its manifest.
I'm trying to run hive from the command prompt it is working absolutely fine. But when I try running hiveserver using "hive --service hiveserver" command, I'm getting the following exception.
Starting Hive Thrift Server

So I then tried with the command "hive --service hiveserver2"; still I'm not finding any solution.
Can anybody please suggest a solution for this problem.
May be another process (another hiveserver) already listening on port 10000.
can you check it by :
netstat -ntulp | grep ':10000' to see it and if found then kill the process.
Otherwise start the server on another port.
By the way which version you are using ?
This error occurred to me when it can't find hive-service-*.jar in hadoop classpath. Just copy the hive-service-*.jar to your hadoop lib folder or export classpath in hadoop-env.sh. I have mentioned how to add classpath below.
Add this line in hadoop-env.sh:
export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:/usr/local/hive/lib/hive-*.jar
I have mentioned the path for hive as /usr/local/hive since i have hive installed at that location. Change it to point to your hive installation.
I am new to Hadoop and I have just setup Hadoop 1.2.1 on my Mac laptop (Mavericks). I then created a simple WordCount project in IntelliJ IDEA and was able to run the code on a dummy text file. I am having trouble with successfully creating a jar file which will replicate my execution through the IDE. I get the following error:
java -jar ./out/artifacts/WordCount_jar/WordCount.jar test.txt out [19:35:21]

Could anyone let me know what I am missing?
I guess you have to specify your class (which implements the Map/Reduce function).
E.g., $ java -jar ./WordCount.jar classWordCount input.txt output
or $ hadoop jar yourprogram.jar **yourclass** inputpath outputpath
By opening the RUN_Adempiere.bat file the following errors will be occured
by opening the RUN_Server2.bat just opened and move on to the invisible mode

Right click on RUN_Server2.bat and run as administrator.
Run the Setup.BAT file first in the source folder and install the Adempiere, Once installed you will be able to solve the following error. Also set the Paths correctly , JAVA_HOME path and ADEMPIERE_HOME path.
I tried to run ./hadoop start-all.sh
Unfortunately this error is thrown

I though it might have been the hadoop path but that does not seem to fix the issue. The path that i set in the hadoop-env.sh is /usr/local/hadoop/bin`.
I looked at other posts with simular titles
Hadoop: strange ClassNotFoundException
what is considered the main class. I tried changing the path to /usr/local/hadoop/bin/
Its a shell script. >> start-all.sh should do. You do not need hadoop. You can find more information here. http://hadoop.apache.org/common/docs/r0.19.2/quickstart.html
Just run as follows
/path/to/Hadoop/home/bin/start-all.sh
In your case
/user/local/hadoop/bin/start-all.sh
Since you are already in /hadoop/bin folder. You no need to give again ./hadoop start-all.sh
instead just give ./start-all.sh
It will not throw any error and it will start your hadoop process.
