-------------------------------------
Hi [~andrewcheng], welcome to report issue to Kylin!
While, I still not understand the requirment: in which case the
"mapreduce.application.classpath" is absent, and still not allow to use local
cmd to get the classpath? Usually Kylin is installed in a Hadoop client node,
which need the MR/Hive/HBase be well configured, the classpath configuration
should be correct for all Hadoop node. Could you please elaborate the problem
you encountered, and how common it is? Thank you!
> Whether to set mapreduce.application.classpath is determined by the user

> 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.
