> --------------------------------------------------------------------------------------

> Key: SPARK-22089
> URL: https://issues.apache.org/jira/browse/SPARK-22089
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.1.0
> Reporter: guichaoxian
>
> the fileStatusCache is globally shared cache，refresh is only for one table，so
> we do not need to invalidateAll entry in fileStatusCache
> {code:java}
> /** Globally shared (not exclusive to this table) cache for file statuses
> to speed up listing. */
> private val fileStatusCache = FileStatusCache.getOrCreate(sparkSession)
> {code}
> {code:java}
> override def refresh(): Unit = {
> refresh0()
> fileStatusCache.invalidateAll()
> }
> {code}
