I think it should be related to this JIRA (https://issues.apache.org/jira/browse/YARN-7269). Seems like a Hadoop 2.9/3.0+ issue. |

The code looks ok, but it also looks similar to this:
I'm wondering if we could just call that class instead, somehow? It seems available in 2.6 which is the oldest version we support.

For the Spark usage, I think it may not be so useful to use AmFilterInitializer, because we need to pass the filter parameters to driver either from RPC (client mode) or from configuration (cluster mode), in either way we should know how to set each parameter, so from my understanding using AmFilterInitializer seems not so useful.

YARN
AmIpFilteradds a new parameter "RM_HA_URLS" to support RM HA, but Spark on YARN doesn't provide a such parameter, so it will be failed to redirect when running on RM HA. The detailed exception can be checked from JIRA. So here fixing this issue by adding "RM_HA_URLS" parameter.How was this patch tested?
Local verification.
