1) use cdh5.8.3 after installing the spark, found the spark role type Gateway shows status to "not applicable", excuse me normal?
2) use cdh5 after installing the spark, don't need some manual configuration file to make gateway according to normal?
3) cdh5 bring the spark at the front desk display gateway state what is right?

Normal phenomenon, the gateway is the spark task submitted entry, only one history server configuration is enough

Feel this state is normal today, make for a long time of the gateway, are not applicable, but also won't affect the program is running, if the spark on yarn to run the operation failure, try not to put the su HDFS, perform under HDFS spark - submit, I feel CDH installed spark (on yarn is the above, there is also a stand-alone version as below) should have a built-in yarn, can be submitted, the default is to use this, so you also need to modify the environment, configure some permissions,
