Affects Versions: 2.0.2
Reporter: Tim Chan
I have a structured stream job running on EMR. The job will fail due to this
```
Multiple HDFSMetadataLog are using s3://mybucket/myapp
org.apache.spark.sql.execution.streaming.HDFSMetadataLog.org$apache$spark$sql$execution$streaming$HDFSMetadataLog$$writeBatch(HDFSMetadataLog.scala:162)

There is only one instance of this stream job running.
