问题 I am able to find the name if the input file in a mapper class using FileSplit when writing the program in Java. Is there a corresponding way to do this when I write a program in Python (using streaming?) I found the following in the hadoop streaming document on apache: See Configured Parameters. During the execution of a streaming job, the names of the "mapred" parameters are transformed. The dots ( . ) become underscores ( _ ). For example, mapred.job.id becomes mapred_job_id and mapred.jar

How does mercurial handle splitted files? What will happen if I create a branch and split a file. Can I easily pull changes from another branch which modifies the original, unsplitted file? After reading the clarification comment, the answer is no. Mercurial tracks files, not hunks of code, so it can't do that as far as I know. I just did a little experiment. I created one repository ( foo ) with one big file. Then I cloned that into bar , used hg cp to copy the file into two files, and removed one half in both files. Then I made a change affecting the whole file in foo , and merged that into

问题 I want to split a file containg HTTP response into two files: one containing only HTTP headers, and one containg the body of a message. For this I need to split a file into two on first empty line (or for UNIX tools on first line containing only CR = ' \r ' character) using a shell script . How to do this in a portable way (for example using sed , but without GNU extensions)? One can assume that empty line would not be first line in a file. Empty line can got to either, none or both of files;

How to file split at a line number [closed]

I want to split a 400k line long log file from a particular line number. For this question, lets make this an arbitrary number 300k. Is there a linux command that allows me to do this ( within the script )? I know split lets me split the file in equal parts either by size or line numbers but that's not what I want. I want to the first 300k in one file and the last 100k in the second file. Any help would be appreciated. Thanks! On second thoughts this would be more suited to the superuser or serverfault site. academicRobot file_name=test.log # set first K lines: K=1000 # line count (N): N=$(wc
