recovery accidently deleted pig script
Hi everyone,
We have a pig script scheduled running every 4 hours. Someone accidentally
deleted the pig script(rm). Is there any way to recover the script?
I am guessing Hadoop copy the program to every nodes before running. Just
in case it has any copy in the nodes.
Best regards,
Feng Jiang

Well if the script was sitting on the cluster... Then it would be a Hadoop question.
?How do you recover a file that was deleted on HDFS?
Which is an interesting question...
But the OP said it wasn't on HDFS, and to your point... One can only say sorry dude, bummer, rewrite it.
Sorry you're having a rough day.
This is why I usually say Embrace the suck.

Hi,
If the pig process is not closed ,try lsof may helpJ
The files used by one process
/proc/<pid>/fd/<file>,use lsof to find full path ,copy the file in memory to disk.
God bless you.

The script is on local file system. it's on linux box.
I totally agree we need version control for the source code. this is a good example to show the importance of version control.
Thank you Michael and Chris for your inputs anyway.

Hi,
If the pig process is not closed ,try lsof may helpJ
The files used by one process
/proc/<pid>/fd/<file>,use lsof to find full path ,copy the file in memory to disk.
God bless you.

The script is on local file system. it's on linux box.
I totally agree we need version control for the source code. this is a good example to show the importance of version control.
Thank you Michael and Chris for your inputs anyway.

Well if the script was sitting on the cluster... Then it would be a Hadoop question.
?How do you recover a file that was deleted on HDFS?
Which is an interesting question...
But the OP said it wasn't on HDFS, and to your point... One can only say sorry dude, bummer, rewrite it.
Sorry you're having a rough day.
This is why I usually say Embrace the suck.

Where was the pig script? On HDFS?
How often does your cluster clean up the trash?
(Deleted stuff doesn't get cleaned up when the file is deleted... ) Its a configurable setting so YMMV
