我正在尝试加载apache日志，将其拆分为字段并保存到hcatalog中。

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);

如果我这样做了：

a = sample apache_row 0.001;
dump a

它起作用了。
但是

store apache_row into 'stage.apache_log' using org.apache.hcatalog.pig.HCatStorer();

不。

我在哪里可以找到这个问题的任何细节？我可以在下面找到更多详细信息：
hadoop1:50030/jobdetails.jsp？jobid=job\u 201402120751\u 0117
但当工作完成后，它就不起作用了。。。
当做
