Summary: There is no need for fileStatusCache to invalidateAll
when InMemoryFileIndex refresh
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}
