Could you update the JIRA title to be more meaningful and provide both compared versions?

> Hi,
> I just observed that when we use dataframe.saveAsTable("table") -- In oldversions
> and dataframe.write.saveAsTable("table") -- in the newer versions
>                 When using the method “df3.saveAsTable("brokentable")” in scale code. This creates a folder in hdfs and doesn’t update hive-metastore that it plans to create the table. So if anything goes wrong in between the folder still exists and hive is not aware of the folder creation. This will block the users from creating the table “brokentable” as the folder already exists, we can remove the folder using “hadoop fs –rmr /data/hive/databases/testdb.db/brokentable”.  So below is the workaround which will enable to you to continue the development work.
> Current Code:
> val df3 = sqlContext.sql("select * fromtesttable")
> df3.saveAsTable("brokentable")
> THE WORKAROUND:
> By registering the DataFrame as table and then using sql command to load the data will resolve the issue. EX:
> val df3 = sqlContext.sql("select * from testtable").registerTempTable("df3")
> sqlContext.sql("CREATE TABLE brokentable AS SELECT * FROM df3")
