[jira] [Created] (KYLIN-3866) Whether to set mapreduce.application.classpath is determined by the user

------------------------------------

             Summary: Whether to set mapreduce.application.classpath is determined by the user
                 Key: KYLIN-3866
                 URL: https://issues.apache.org/jira/browse/KYLIN-3866
             Project: Kylin
          Issue Type: Bug
            Reporter: Guangxu Cheng


In the kylin environment, if there is no configuration parameter "mapreduce.application.classpath", then kylin will use the command "mapred classpath" to get the local classpath and set it to "mapreduce.application.classpath", However, it will cause the following two problems:
1. The local classpath may not be the same as the MapReduce cluster.
2. There is no need to configure the parameter "mapreduce.application.classpath" on the client side in some cluster.

So, it may be a better choice for users to decide whether they need to configure this parameter or not.
