Description

The following command fails when data1 contains a 3gb file. It passes when using hftp or when the directory just contains smaller (<2gb) files, so looks like a webhdfs issue with large files.

hadoop distcp webhdfs://eli-thinkpad:50070/user/eli/data1 hdfs://localhost:8020/user/eli/data2
