Question

我正在安装Hadoop / Pig / Thrift / Hive。到目前为止，我已经完成了所有工作，但是当我创建一个包含Serde的表时，我遇到了一个问题。这实际上是来自Hive的官方文档的复制/粘贴。

谁能告诉我它有什么问题？

add jar /opt/hadoop/hive-0.11.0-bin/lib/hive-contrib-0.11.0.jar;

CREATE TABLE apachelog (
  host STRING,
  identity STRING,
  user STRING,
  time STRING,
  request STRING,
  status STRING,
  size STRING,
  referer STRING,
  agent STRING)
ROW FORMAT SERDE 'org.apache.hadoop.hive.contrib.serde2.RegexSerDe'
WITH SERDEPROPERTIES (
  "input.regex" = "([^]*) ([^]*) ([^]*) (-|\\[^\\]*\\]) ([^ \"]*|\"[^\"]*\") (-|[0-9]*) (-|[0-9]*)(?: ([^ \"]*|\".*\") ([^ \"]*|\".*\"))?",
  "output.format.string" = "%1$s %2$s %3$s %4$s %5$s %6$s %7$s %8$s %9$s"
)
STORED AS TEXTFILE;

我在执行此操作时遇到的错误是：

hadoop@ux03:~# hive -f queries/web_logs.hive

您的正则表达式中似乎缺少空格：

"input.regex" = "([^ ]*) ([^ ]*) ([^ ]*) (-|\\[[^\\]]*\\])
([^ \"]*|\"[^\"]*\") (-|[0-9]*) (-|[0-9]*)(?: ([^ \"]*|\"[^\"]*\")
([^ \"]*|\"[^\"]*\"))?"

请确保您的正则表达式正确无误。

Hive的教程不起作用？
