在hadoop流式传输期间需要有关调试权限问题的帮助。我尝试启动awk流媒体：

// mkdir到所有节点

[pocal@oscbda01 ~]$  for i in  01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 ;  do ssh -f oscbda$i mkdir -p /home/pocal/KS/comverse/awk/; done;

//将流文件复制到所有节点

[pocal@oscbda01 ~]$  for i in  01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 ;  do scp * oscbda$i:/home/pocal/KS/comverse/awk/; done;

//为所有文件提供777权限

[pocal@oscbda01 ~]$  for i in  01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 ;  do ssh -f oscbda$i chmod 777 /home/pocal/KS/comverse/awk/*; done;

//开始流式传输

[pocal@oscbda01 ~]$ hadoop fs -rm -r /user/pocal/ks/comverse/one/out;\
hadoop jar  /usr/lib/hadoop-mapreduce/hadoop-streaming-2.0.0-cdh4.3.0.jar \
-Dmapreduce.job.reduces=0 \
-Dmapred.reduce.tasks=0 \
-mapper "awk -f /home/pocal/KS/comverse/awk/data_change.awk -f /home/pocal/KS/comverse/awk/selfcare.awk -f /home/pocal/KS/comverse/awk/selfcare_secondary_mapping.awk -f /home/pocal/KS/comverse/awk/out_sort.awk" \
-input "/user/pocal/ks/comverse/one/" \
-output "/user/pocal/ks/comverse/one/out"

得到错误......

检查一台机器：

[pocal@oscbda01 ~]$ ssh oscbda10 ls -l /home/pocal/KS/comverse/awk/data_change.awk
-rwxrwxrwx 1 pocal pocal 1548 Dec 10 10:05 /home/pocal/KS/comverse/awk/data_change.awk

权限确定...

有人有任何想法吗？

是父目录的问题：

Add permission:
[pocal@oscbda01 .ssh]$ for i in  01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 ;  do ssh -f oscbda$i chmod +x /home/pocal; done;
Check:
[pocal@oscbda01 .ssh]$ ssh oscbda05 ls -l /home/|grep poc
drwx--x--x 5 pocal  pocal    4096 Dec 10 09:52 pocal

它有效！
