Hadoop Module List Files Example

TOC

List recursively through a directory and its sub-directories (except hidden directories)

ctx.hdfs.list 'mydir', { file -> println file }

//do for for cluster A and cluster B
ctx.hdfs.list 'a', 'mydir', { file -> println file }
ctx.hdfs.list 'b', 'mydir', { file -> println file }

List non-recursively through a directory

    ctx.hdfs.list 'mydir', false, { file -> println file }
