[jira] [Created] (CRAIL-110) ClassNotFoundException when running Crail

jhli created CRAIL-110:
--------------------------

             Summary: ClassNotFoundException when running Crail
                 Key: CRAIL-110
                 URL: https://issues.apache.org/jira/browse/CRAIL-110
             Project: Apache Crail
          Issue Type: Bug
    Affects Versions: 1.2
            Reporter: jhli


I'm running the incubating Crail of version 1.2. I build successfully using "mvn -DskipTests install", and also copy the configuration files. However when I run the bin/crail, it tolds me that some classes are not found. What may be the possible reasons?

Another question: If my machine does not support RDMA, is it possible to just run Crail in a standalone mode (e.g., TCP backed by DRAM), and read/write files just like HDFS?
