gatorsmile 65b10ffb38 [SPARK-19279][SQL] Infer Schema for Hive Serde Tables and Block Creating a Hive Table With an Empty Schema ... ### What changes were proposed in this pull request? So far, we allow users to create a table with an empty schema: `CREATE TABLE tab1`. This could break many code paths if we enable it. Thus, we should follow Hive to block it. For Hive serde tables, some serde libraries require the specified schema and record it in the metastore. To get the list, we need to check `hive.serdes.using.metastore.for.schema,` which contains a list of serdes that require user-specified schema. The default values are - org.apache.hadoop.hive.ql.io.orc.OrcSerde - org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe - org.apache.hadoop.hive.serde2.columnar.ColumnarSerDe - org.apache.hadoop.hive.serde2.dynamic_type.DynamicSerDe - org.apache.hadoop.hive.serde2.MetadataTypedColumnsetSerDe - org.apache.hadoop.hive.serde2.columnar.LazyBinaryColumnarSerDe - org.apache.hadoop.hive.ql.io.parquet.serde.ParquetHiveSerDe - org.apache.hadoop.hive.serde2.lazybinary.LazyBinarySerDe ### How was this patch tested? Added test cases for both Hive and data source tables Author: gatorsmile <gatorsmile@gmail.com> Closes #16636 from gatorsmile/fixEmptyTableSchema.		2017-02-06 13:30:07 +08:00
