Description

Set erasure coding policy to an existing 3x replication file, or change the current existing erasure coding policy of an existing file to another erasure coding policy will force the file to been transformed from one redundancy layout into another one. The converting usually will be time consuming. This task is to provide a new tool or improve an existing tool to facilitate the HDFS administrator to smooth this converting process.
