我正在尝试加载 apache 日志，拆分为字段并将其保存到 hcatalog。
apache_log = LOAD 'httpd-www01-access.log.2014-02-09-*' USING TextLoader AS (line:chararray);
apache_row = FOREACH apache_log GENERATE FLATTEN (
REGEX_EXTRACT_ALL
(line,'^"(\\S+)" \\[(\\d{2}\\/\\w+\\/\\d{4}:\\d{2}:\\d{2}:\\d{2} \\+\\d{4}]) (\\S+) (\\S+) "(.+?)" (\\S+) (\\S+) "([^"]*)" "([^"]*)" "([^"]*)"'))
AS (ip: chararray, datetime: chararray, session_id: chararray, time_of_request:chararray, request: chararray, status: chararray, size: chararray, referer : chararray, cookie: chararray, user_agent: chararray);
如果我做：
a = sample apache_row 0.001;
dump a
有用。
但
store apache_row into 'stage.apache_log' using org.apache.hcatalog.pig.HCatStorer();
没有。

我在哪里可以找到问题的任何细节？有一个信息，我可以在下面找到更多详细信息：

但是当工作完成时它不起作用......
问候
