We are having a strange issue while trying to pump large amount of data using distcp to another cluster .
I have moved this post to the HDFS discussion board in hopes that someone in here can assist you with this question. I think we may need to change the name of the original board you posted this to as it is confusing. It is called "Data Ingestion...", but is specifically aimed at tools like Sqoop, Flume, etc. WebHDFS and distcp are HDFS components, so I hope you can find some help in this board.
