Cannot execute YCSB

[ChristianNavolskyi]

Hello, I have some problem executing YCSB.

I have cloned the repository and packaged everything via

mvn clean package

but when I try to run it by

bin/ycsb.sh load basic -P workloads/workloada

it prints

/usr/bin/java -classpath /Users/navolskyi/Desktop/YCSB/conf:/Users/navolskyi/Desktop/YCSB/core/target/core-0.14.0-SNAPSHOT.jar:/Users/navolskyi/Desktop/YCSB/core/target/core-0.14.0-SNAPSHOT.jar com.yahoo.ycsb.Client -load -db com.yahoo.ycsb.BasicDB -P workloads/workloada
Command line: -load -db com.yahoo.ycsb.BasicDB -P workloads/workloadaYCSB Client 0.14.0-SNAPSHOT

I am using macOS version 10.13.3 and Maven version 3.5.0.

As far as I can tell the shell script does not include the needed dependencies in the classpath.

This sounds like #908. Could you try downloading and using our last release's binaries?

In the event that you need some functionality that isn't in a release yet, could you try using the python script bin/ycsb?

When I run the benchmark from the binary everything works as expected.

Running it with the python script works within my IDE, strange that the other scripts don't work.

When I build the source by myself with mvn clean package extract it and run ./bin/ycsb.sh load basic -P workloads/workloada it also works.

I am using IntelliJ and I can run the benchmark with a binding by setting "Use classpath of module" to the module of the binding.

[ChristianNavolskyi]

I think the problem is, that the dependencies from the core module are not included in the build core.jar.
The ycsb.sh script only uses the target/dependency folder for the bindings.

So eighter the dependencies should be built, packaged in the target folder and the script looks it up there or the dependencies should be included in the core.jar.

Thanks! I think that confirms that this is the same issue as #908. That PR is just waiting on a test on the windows side for merge.

#908 has merged now. would you mind trying again?

closing as stale. if you're still having trouble please reopen.
