Spark SQL error from EMR notebook with AWS Glue table partition

Question

I'm testing some pyspark code in an EMR notebook before I deploy it and keep running into this strange error with Spark SQL. I have all my tables and metadata integrated with the AWS Glue catalog so that I can read and write to them through spark.

The first part of the code reads some data from S3/Glue, does some transformations and what not, then writes the resulting dataframe to S3/Glue like so:

df.repartition('datekey','coeff')\
    .write\
    .format('parquet')\
    .partitionBy('datekey','coeff')\
    .mode('overwrite')\
    .option("path", S3_PATH)\
    .saveAsTable('hive_tables.my_table')

I then try to access this table with Spark SQL, but when I run something as simple as spark.sql('select * from hive_tables.my_table where datekey=20210506').show(), it throws this:

An error was encountered:
"org.apache.hadoop.hive.metastore.api.InvalidObjectException: Unknown type : 'double' (Service: AWSGlue; Status Code: 400; Error Code: InvalidInputException; Request ID: 43ff3707-a44f-41be-b14a-7b9906d8d8f9; Proxy: null);"

I've learned this happens only when specifying the datekey partition. For example, both of the following commands work fine: spark.sql('select * from hive_tables.my_table where coeff=0.5').show() and spark.sql('select * from hive_tables.my_table').show()

I've verified through Spark SQL that the partitions exist and have data in them. The datekey query also works fine through AWS Athena - just not Spark SQL.

Also Glue definitely has the two partition columns recognized:

datekey: int
coeff: double

Any ideas here? I've tried everything I can think of and it just isn't making any sense.

Answer 1

I would still like a straight-forward solution to this, but currently this workaround suffices:

I first read the table straight from the S3 path

temp_df = spark.read.parquet(S3_PATH)

so that it doesn't use the Glue catalog as the metadata. Then I create a temp table for the session:

temp_df.createGlobalTempView('my_table')

which allows me to query it using Spark SQL with the global_temp database:

spark.sql('select * from global_temp.my_table where datekey=20210506').show()

and this works

Answer 2

I had same error In emr 6.3.0 (Spark 3.1.1).

After upgrade to emr 6.5.0 (Spark 3.1.2), It solved.
