Re: tab-delimited output

[Alan Miller]

Hi Alex,

The tab isn't the issue (yet). I guess it's really 2 questions I have.
Using the reducer inputs already mentioned.

1. How do I generate multiple output files named YYYY-MM-DD.txt
2. Each file should contain
     a. one line per host
     b. each line with host avg1 avg2 avg3 ....

Hi Alan,

Is the problem that you want your 'value' vals to be tab separated? This is entirely under control of your reducer.

    Hi all,

    How can I write tab-delimited output files from my reducer?

    My reducer gets Text/Text key/vals like:

    hostX_2010-05-01 varA=valA1,varB=valB1,varC=valC1
    hostX_2010-05-01 varA=valA2,varB=valB2,varC=valC2
    hostX_2010-05-01 varA=valA3,varB=valB3,varC=valC3
    ...
    hostY_2010-05-01 varA=valA1,varB=valB1,varC=valC1
    hostY_2010-05-01 varA=valA2,varB=valB2,varC=valC2
    hostY_2010-05-01 varA=valA3,varB=valB3,varC=valC3
    ...

    After my reducer calcs the daily averages of varA,B,C
    I  want to write a tab-delimited file with lines like:

    hostX    varA-Avg    varB-Avg    varC-Avg    ....
    hostY    varA-Avg    varB-Avg    varC-Avg    ....


    Thanks,
