--------------------------------------
Summary: Review Spark's handling of filesystems returning
"localhost" in getFileBlockLocations
Key: SPARK-20560
URL: https://issues.apache.org/jira/browse/SPARK-20560
Project: Spark
Issue Type: Bug
Components: Scheduler
Affects Versions: 2.1.0
Reporter: Steve Loughran
Priority: Minor
Some filesystems (S3a, Azure WASB) return "localhost" as the response to
{{FileSystem.getFileBlockLocations(path)}}. If this is then used as the
preferred host when scheduling work, there's a risk that work will be queued on
one host, rather than spread across the cluster.
HIVE-14060 and TEZ-3291 have both seen it in their schedulers.
I don't know if Spark does it, someone needs to look at the code, maybe write
some tests
