hadoop - Apache PIG - How to change the standard output name "part-r-00000" of files? -


i have .pig script creates file calculated data. want have output file named "result.txt" instead of meaningless standard output name "part-r-00000".

the last entry in .pig script

store c 'result' using pigstorage();

therefore "result" name of folder in hdfs result.txt should stored.

how can this?

the part-r-xxxxx not meaningless depending on how plan use them. if need load results of pig script pig script can do:

a = load 'result' using pigstorage() (...) ;

as load can take directory input , load each file in directory.

if need handle output (locally) single text file, there nothing builtin pig accomplish that. need write script pull results hdfs , concatenate of part-r-xxxxx files together.
