[SPARK-3657] yarn alpha YarnRMClientImpl throws NPE
appMasterRequest.setTrackingUrl starting spark-shell
@tgraves reported this issue.
Following is quoted from @tgraves' report.
YarnRMClientImpl.registerApplicationMaster can throw null pointer exception
when setting the trackingurl if its empty:
appMasterRequest.setTrackingUrl(new URI(uiAddress).getAuthority())
I hit this just start spark-shell without the tracking url set.
