[GitHub] [incubator-kyuubi] pan3793 commented on pull request #1119: [KYUUBI #1039] Kill yarn job when engine initialize timeout and yarnApplicationState is ACCEPTED

   So far, there are 3 approaches to kill yarn applications
   
   1. Execute command `yarn kill $app_name`
   2. Use Yarn RestFul API
   3. Use Yarn client
   
   Personally, I prefer option 2, then option 1.
   
   Option 1 requires the user to set up Hadoop client on the Kyuubi server node(s), and also set `HADOOP_HOME`, suppose that the user usually should deploy Kyuubi on the Hadoop node, it's acceptabe.
   
   If we choose option 3, we need to test with different versions of Yarn cluster to ensure that the compatibility between Kyuubi server bundled Hadoop client jars and Yarn cluster.
   
   Seems that option 2 has less dependencies and good compatibility.
   
   @timothy65535 @simon824 @zhouyifan279 @yaooqinn WDYT?
