> Spark 1.6.1 and 1.6.2 is not able to read data from a table after the table has been renamed. This can be reproduced with the following actions in the spark-shell:
> sqlContext.sql("SELECT 1 as col1, 2 as col2").write.format("parquet").mode("overwrite").saveAsTable("mytesttable")
> sqlContext.sql("SELECT * FROM mytesttable").show()
> +----+----+
> |col1|col2|
> +----+----+
> |   1|   2|
> +----+----+
> sqlContext.sql("ALTER TABLE mytesttable RENAME TO mytesttable_withnewname")
> sqlContext.sql("SELECT * FROM mytesttable_withnewname").show()
> +----+----+
> |col1|col2|
> +----+----+
> +----+----+
> I believe the issue is related to SPARK-14920 and SPARK-15635 - Spark stores (and later retrieves) a location of a table to a "path" SerDe property, which is not modified in HiveMetaStore's alter_table. And as the actual directory on HDFS is renamed, the "path" doesn't point to a correct location after the update.
