--------------------------------
Summary: failed to uncache datasource table after the table
location altered
Key: SPARK-19845
URL: https://issues.apache.org/jira/browse/SPARK-19845
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.2.0
Reporter: Song Jun
Currently if we first cache a datasource table, then we alter the table
location,
then we drop the table, uncache table will failed in the DropTableCommand,
because the location has changed and sameResult for two InMemoryFileIndex with
different location return false, so we can't find the table key in the cache.
