Apache Spark reassigned SPARK-27555:
------------------------------------
Assignee: Apache Spark
> cannot create table by using the hive default fileformat in both
> hive-site.xml and spark-defaults.conf
> ------------------------------------------------------------------------------------------------------
>
> Key: SPARK-27555
> URL: https://issues.apache.org/jira/browse/SPARK-27555
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.3.2
> Reporter: Hui WANG
> Assignee: Apache Spark
> Priority: Major
> Attachments: Try.pdf
>
>
> *You can see details in attachment called Try.pdf.*
> I already seen https://issues.apache.org/jira/browse/SPARK-17620
> and https://issues.apache.org/jira/browse/SPARK-18397
> and I check source code of Spark for the change of set
> "spark.sql.hive.covertCTAS=true" and then spark will use
> "spark.sql.sources.default" which is parquet as storage format in "create
> table as select" scenario.
> But my case is just create table without select. When I set
> hive.default.fileformat=parquet in hive-site.xml or set
> spark.hadoop.hive.default.fileformat=parquet in spark-defaults.conf, after
> create a table, when i check the hive table, it still use textfile fileformat.
>
> It seems HiveSerDe gets the value of the hive.default.fileformat parameter
> from SQLConf
> The parameter values in SQLConf are copied from SparkContext's SparkConf at
> SparkSession initialization, while the configuration parameters in
> hive-site.xml are loaded into SparkContext's hadoopConfiguration parameters
> by SharedState, And all the config with "spark.hadoop" conf are setted to
> hadoopconfig, so the configuration does not take effect.
