TProtocolException: Required field 'type' is unset! Struct:TPrimitiveTypeEntry(type:null)
org.apache.thrift.protocol.TProtocolException:
Required field 'type' is unset! Struct:TPrimitiveTypeEntry(type:null)
在查询hive数据库时,由于查询出的一些字段为null,
不是String的空,是null,需要额外做一下处理,
IsNull(可能为null的字段名, '') AS "别名"
这破问题憋了我三四天,真的恶心。
还有,hive没有delete方法,所谓的删除方法只是将一些数据拿出来,
清空该表,再将这些数据insert进去
