Hello, List! I have several files in HDFS in a single directory that I create throughout the day. At the end of the day, I want to merge them together into one file. How do you guys do this?
It seems this would do it: hadoop fs -getmerge /hdfs/directory/allsource* > mergefile ; cat mergefile | hadoop fs -put - ; rm mergefile ; hadoop fs -rm /hdfs/directory/allsource* But I wonder if there's a command that can avoid writing to the local filesystem then re-writing back into HDFS. I'm looking for an HDFS equivalent to this Unix script: cat /some/dir/allsource* > /some/dir/merged ; rm /some/dir/allsource* -- Tim Ellis Data Architect, Riot Games
