在《鲨鱼》里，当我奔跑时：

CREATE EXTERNAL TABLE test (
  memberId STRING,
  category STRING,
  message STRING,
  source STRING,
  event_type STRING,
  log_level STRING,
  path STRING,
  host STRING,
  event_timestamp STRING,
  eventFields MAP<STRING,STRING>
)
PARTITIONED BY (datePart STRING)
ROW FORMAT SERDE 'com.company.eventserde.EventSerde'
LOCATION '/user/ubuntu/test';

我得到：

[Hive Error]: Query returned non-zero code: 1, cause: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask
Time taken (including network latency): 0.05 seconds

错误日志显示：

有人知道为什么shark不在hadoop中创建表吗？
