saturday_s · Marcelo Vanzin · commit e92ffe6f1771 · 2017-06-19T10:24:29.000-07:00
## What changes were proposed in this pull request? Reload the `spark.yarn.credentials.file` property when restarting a streaming application from checkpoint. ## How was this patch tested? Manual tested with 1.6.3 and 2.1.1. I didn't test this with master because of some compile problems, but I think it will be the same result. ## Notice This should be merged into maintenance branches too. jira: [SPARK-21008](https://issues.apache.org/jira/browse/SPARK-21008) Author: saturday_s <shi.indetail@gmail.com> Closes #18230 from saturday-shi/SPARK-21008.
