I'm getting clusters by cloudera-manager-api.
I'm using Maven shade-plugin .
There is another question relating to null pointer exceptions, but this doesn't solve my particular problem. It looks like a dependency issue because if I run the app in my IDE it works fine.
When I run the self-packaged jar it fails, What dependency could I be missing?
source is below
String host = HOST_PREFIX + args[0];
String command = args[1];
RootResourceV10 apiRoot = new ClouderaManagerClientBuilder()
.withHost(host).withPort(7180)
.withUsernamePassword(ADMIN, ADMIN).build().getRootV10();
if (apiRoot == null) {
System.exit(0);
}
ClustersResourceV10 clusterResource = apiRoot.getClustersResource();
try {
if (command.equals(START)) {
System.out.println("starting..");
ApiCommand cmd = apiRoot.getClustersResource().startCommand(
"cluster"
);
while (cmd.isActive()) {
cmd = apiRoot.getCommandsResource()
.readCommand(cmd.getId());
}
} else {
System.out.println("stopping..");
ApiCommand cmdstop = apiRoot.getClustersResource().stopCommand(
"cluster"
);
while (cmdstop.isActive()) {
cmdstop = apiRoot.getCommandsResource().readCommand(
cmdstop.getId());
}
}
} catch (NullPointerException e) {
e.printStackTrace();
}
}
Error message is below {
java.lang.NullPointerException
