> Add a Distcp option to preserve Erasure Coding attributes
> ---------------------------------------------------------
>
> Key: HADOOP-14254
> URL: https://issues.apache.org/jira/browse/HADOOP-14254
> Project: Hadoop Common
> Issue Type: Improvement
> Components: tools/distcp
> Affects Versions: 3.0.0-alpha4
> Reporter: Wei-Chiu Chuang
> Priority: Major
> Attachments: HADOOP-14254-01.patch, HADOOP-14254-02.patch,
> HADOOP-14254-03.patch, HADOOP-14254-04.patch, HADOOP-14254.test.patch,
> HDFS-11472.001.patch
>
>
> Currently Distcp does not preserve the erasure coding attributes properly. I
> propose we add a "-pe" switch to ensure erasure coded files at source are
> copied as erasure coded files at destination.
> For example, if the src cluster has the following directories and files that
> are copied to dest cluster
> hdfs://src/ root directory is replicated
> hdfs://src/foo erasure code enabled directory
> hdfs://src/foo/bar erasure coded file
> after distcp, hdfs://dest/foo and hdfs://dest/foo/bar will not be erasure
> coded.
> It may be useful to add such capability. One potential use is for disaster
> recovery. The other use is for out-of-place cluster upgrade.
