我使用這個命令試過，我得到錯誤星火1.4.1 - 使用pyspark
代碼
instances = sqlContext.sql("SELECT instance_id ,instance_usage_code
FROM ib_instances WHERE (instance_usage_code) = 'OUT_OF_ENTERPRISE' ")
instances.write.format("orc").save("instances2")
hivectx.sql(""" CREATE TABLE IF NOT EXISTS instances2 (instance_id
string, instance_usage_code STRING)""")
hivectx.sql (" LOAD DATA LOCAL INPATH '/home/hduser/instances2' into
table instances2 ")
錯誤
