Hello,I would like to ask you if it is possible to create and work with a temporary file while in a map function.
I suppose that map function is running on a single node in Hadoop cluster. So what is a safe way to create a temporary file and read from it in one map() run. If it is possible is there a size limit for the file.
The file can not be created before hadoop job is created. I need to create and process the file inside map().
Thanks for your answer. Ondrej Klimpera.
