Question

```It is possible the underlying files have been updated You can explicitly invalidate the cache in Spark by running REFRESH TABLE tableName command in SQL or by recreating the Dataset DataFrame involved ``` How it can be possible to have a file name cached in spark We are getting a strange error regarding ``` java io FileNotFoundException No such file or directory s3a snappy parquet``` I restarted the app but still the same issue I checked delta logs and the file is not present in delta log How is spark able to remember this file when it is not even present in delta log
