> Key: SPARK-19577
> URL: https://issues.apache.org/jira/browse/SPARK-19577
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.2.0
> Reporter: Song Jun
>
> If we use InMemoryCatalog, then we insert into a partition datasource table,
> which partition location has changed by `alter table t partition(a="xx") set
> location $newpath`, the insert operation is ok, and the data can be insert
> into $newpath, while if we then select partition from the table, it will not
> return the value we inserted.
> The reason is that the InMemoryFileIndex to inferPartition by the table's
> rootPath, it does not track the user specific $newPath which provided by
> alter command.
