Question

以下执行代码会在PIG中弹出错误，指出 ERROR 2017：内部错误创建作业配置。。

data = LOAD 'info.txt' USING PigStorage();

name_col_one = FOREACH data GENERATE $0 AS timeStamp, $1 AS one, $2 AS two, $3 AS info, $4 AS four, $5 AS five, $6 AS six, $7 AS seven, $8 AS eight, $9 AS nine, $10 AS ten, $11  AS eleven;

process_col_one = FOREACH name_col_one GENERATE FLATTEN(STRSPLIT(timeStamp,'\\s+',2)) AS (time:chararray, date:chararray), one, two;

new_timestamp = FOREACH process_col_one GENERATE CONCAT(date,CONCAT(' ',time)), one, two;

sys_info = FOREACH name_col_one GENERATE info;

split_  = FOREACH sys_info GENERATE REPLACE(info, '\\[', '') AS new_split;
split_again  = FOREACH split_ GENERATE REPLACE(new_split, ']', '\t') AS final_split;

others = FOREACH name_col_one GENERATE four, five, six, seven, eight, nine, ten, eleven;

r1 = RANK new_timestamp;
r2 = RANK split_again;
r3 = RANK others;

final = JOIN r1 BY rank_new_timestamp, r2 BY rank_split_again;
DUMP final;

在info.txt中采样数据

23:58:19 02/23/2015 good 1042559519 [Linux] [Baseline] [lrtp2nosqlprod1] [FileSystem] [/ tmp] FileSystems / tmp \ Use％= 1％9：5603 0 1

23:58:15 02/23/2015 good 1042559537 [Linux] [Baseline] [lrtp2nosqlprod1] [Process] [srmclient] [SiSExclude]运行3：5599运行true无数据1 0 0

23:58:15 02/23/2015 good 1042559537 [Linux] [Baseline] [lrtp2nosqlprod1] [Process] [OSWatcher] [SiSExclude]正在运行，2个进程4：5599正在运行true无数据2 0 0

关系 new_timestamp正在反转输入数据的时间戳， split_again正在删除$ 3中的方括号，并用'\ t'分隔它们。

此问题已在之前报告过（https://issues.apache.org/jira/browse/PIG-3469）并已修复，可能尝试使用最新版本的猪。

有时可以通过指定输入数据文件的路径来解决此问题例如'/home/user/doc/info.txt'
