Yuming Wang resolved SPARK-24096.
---------------------------------
Resolution: Duplicate
> create table as select not using hive.default.fileformat
> --------------------------------------------------------
>
> Key: SPARK-24096
> URL: https://issues.apache.org/jira/browse/SPARK-24096
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.3.0
> Reporter: StephenZou
> Priority: Major
>
> In my spark conf directory, hive-site.xml have an item indicating orc is the
> default file format.
> <property>
> <name>hive.default.fileformat</name>
> <value>orc</value>
> </property>
>
> But when I use "create table as select ..." to create a table, the output
> format is plain text.
> It works only I use "set hive.default.fileformat=orc"
>
> Then I walked through the spark code and found in
> sparkSqlParser:visitCreateHiveTable(),
> val defaultStorage = HiveSerDe.getDefaultStorage(conf) the conf is SQLConf,
> that explains the above observation,
> "set hive.default.fileformat=orc" is put into conf map, hive-site.xml is not.
>
> It's quite misleading, How to unify the settings?
>
