------------------------------------
Summary: File stream source cleanup options may break a file sink
output
Key: SPARK-29953
URL: https://issues.apache.org/jira/browse/SPARK-29953
Project: Spark
Issue Type: Bug
Components: Structured Streaming
Affects Versions: 3.0.0
Reporter: Shixiong Zhu
SPARK-20568 added options to file streaming source to clean up processed files.
However, when applying these options to a directory that was written by a file
streaming sink, it will make the directory not queryable any more.
I think we should block the options if the input source is a file streaming
sink path (has "_spark_metadata" folder).
