format

I have two files with different data formats in HDFS. How would a job set up look like, if I needed to reduce across both data files? e.g. imagine the common word count problem, where in one file you have space as the world delimiter and in another file the underscore. In my approach I need different mappers for the various file formats, that than feed into a common reducer. How to do that? Or is there a better solution than mine? Donald Miner Check out the MultipleInputs class that solves this exact problem. It's pretty neat-- you pass in the InputFormat and optionally the Mapper class. If

I have function that processes some data and I would like to print the intermediate steps while the function (a loop) proceeds. I could do that in 1 point where the updated data is all in one data.frame() . I'm thinking of some simple table as for example I saw as part of Rapporter tool box. So the question is how or whether it is possible to print table with numerical values into console. Thanks. EDIT: print() is not the solution I'm after and here is why: function print() prints the numeric values into console, but its a messy bunch of numbers. I would like to have kind of table to easily

I have a date that is passed into my JQGrid via a Json string and it looks like "31/10/2011" I cannot work out the formatting via the JQGrid documentation . I just want it to appear and then be sortable in the grid. If I post without formatting, the date looks fine but is not recognised as a date, thus the sorting is all wrong. If I add the following date formatting to the column formatter: 'date', formatoptions: { newformat: 'd/m/Y'} I am getting a date back that looks like this 03/10/2031 I cannot for the life of me work out what the problem is please help. formatter: 'date', formatoptions:
