             Summary: hive.default.fileformat=orc does not set OrcSerde
                 Key: SPARK-17620
                 URL: https://issues.apache.org/jira/browse/SPARK-17620
             Project: Spark
          Issue Type: Bug
          Components: SQL
            Reporter: Brian Cho
            Priority: Minor


Setting {{hive.default.fileformat=orc}} does not set OrcSerde. This behavior is inconsistent with {{STORED AS ORC}}. This means we cannot set a default behavior for creating tables using orc.

The behavior using stored as:

{noformat}
scala> spark.sql("CREATE TABLE tmp_stored_as(id INT) STORED AS ORC")
res0: org.apache.spark.sql.DataFrame = []

scala> spark.sql("DESC FORMATTED tmp_stored_as").collect.foreach(println)
...
[# Storage Information,,]
[SerDe Library:,org.apache.hadoop.hive.ql.io.orc.OrcSerde,]
[InputFormat:,org.apache.hadoop.hive.ql.io.orc.OrcInputFormat,]
[OutputFormat:,org.apache.hadoop.hive.ql.io.orc.OrcOutputFormat,]
...
{noformat}

Behavior setting default conf (SerDe Library is not set properly):

{noformat}
scala> spark.sql("SET hive.default.fileformat=orc")
res2: org.apache.spark.sql.DataFrame = [key: string, value: string]

scala> spark.sql("CREATE TABLE tmp_default(id INT)")
res3: org.apache.spark.sql.DataFrame = []

scala> spark.sql("DESC FORMATTED tmp_default").collect.foreach(println)
...
[# Storage Information,,]
[SerDe Library:,org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe,]
[InputFormat:,org.apache.hadoop.hive.ql.io.orc.OrcInputFormat,]
[OutputFormat:,org.apache.hadoop.hive.ql.io.orc.OrcOutputFormat,]
...
{noformat}
