You can use the linux command hadoop fs -put to push files from local filesystem, and -get to retrieve files
http://hadoop.apache.org/common/docs/r0.20.0/hdfs_shell.html#put http://hadoop.apache.org/common/docs/r0.20.0/hdfs_shell.html#get These work fine for single files or one-offs- if you need to write larger volumes, or concatenate files, or want a higher degree of durability, you might want to look at something like Flume ( https://github.com/cloudera/flume/wiki) or some of the vendor solutions like MapR's.
