I need to transfer files 2-5 GB (in different directories).
Any help/ link much appreciated.
Thanks much in advance and please let me know if you need more info.
Since the question was asked, the situation has changed. As soon as Hortonworks and Cloudera merged, NiFi became supported by Cloudera.
Shortly after the integrations with CDH were also completed, so that NiFi is now a fully supported and integrated component.
Hence the exisint answer already points you in the right direction: NiFi is likely the best fit for solving these usecases.
