错误样例：
CREATE TABLE wangriyu_bugtt1(
task_no int,
exec_ip int)
ROW FORMAT SERDE 'org.apache.hadoop.hive.ql.io.orc.OrcSerde'
STORED AS ORC
报错：
Error in query:
Operation not allowed: ROW FORMAT SERDE is incompatible with format 'orc', which also specifies a serde(line 1, pos 0)
原因：
spark建orc表会自动使用ROW FORMAT SERDE 'org.apache.hadoop.hive.ql.io.orc.OrcSerde'，不需要显示指定。
解决方案：
CREATE TABLE wangriyu_bugtt1(
task_no int,
exec_ip int)ROW FORMAT SERDE 'org.apache.hadoop.hive.ql.io.orc.OrcSerde'
STORED AS ORC
