> {code}
> alter table s3_tbl exchange partition (country='USA', state='CA') with table hdfs_tbl;
> {code}
> results in:
> {code}
> Error: Error while processing statement: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. MetaException(message:Got exception: java.lang.IllegalArgumentException Wrong FS: s3a://hive-on-s3/s3_tbl/country=USA/state=CA, expected: hdfs://localhost:9000) (state=08S01,code=1)
> {code}
> because the check for whether the s3 destination table path exists occurs on the hdfs filesystem.
> Furthermore, exchanging between s3 to hdfs fails because the hdfs rename operation is not supported across filesystems. Fix uses copy + deletion in the case that the file systems differ.
