-----------------------------------
Summary: Support CREATE TABLE LIKE FILE for PARQUET
Key: HIVE-26395
URL: https://issues.apache.org/jira/browse/HIVE-26395
Project: Hive
Issue Type: New Feature
Components: HiveServer2
Reporter: John Sherman
Assignee: John Sherman
The intent is to allow a user to create a table and derive the schema from a
user provided parquet file. A secondary goal is to generalize this support so
other SerDes/formats could implement the feature easily.
The proposed syntax is:
CREATE TABLE <tableName> LIKE FILE <fileFormat> 'path to file';
Example being:
{code:java}
CREATE TABLE like_test_all_types LIKE FILE PARQUET
'${system:test.tmp.dir}/test_all_types/000000_0';{code}
with partitioning
{code}
CREATE TABLE like_test_partitioning LIKE FILE PARQUET
'${system:test.tmp.dir}/test_all_types/000000_0' PARTITIONED BY (year STRING,
month STRING);
{code}
