> Hadoop DistCp supports specifying favoredNodes for data copying
> ---------------------------------------------------------------
>
> Key: HADOOP-18629
> URL: https://issues.apache.org/jira/browse/HADOOP-18629
> Project: Hadoop Common
> Issue Type: New Feature
> Components: tools/distcp
> Affects Versions: 3.3.4
> Reporter: zhuyaogai
> Priority: Major
> Labels: pull-request-available
>
> When importing large scale data to HBase, we always generate the hfiles with
> other Hadoop cluster, use the Distcp tool to copy the data to the HBase
> cluster, and bulkload data to HBase table. However, the data locality is
> rather low which may result in high query latency. After taking a compaction
> it will recover. Therefore, we can increase the data locality by specifying
> the favoredNodes in Distcp.
> Could I submit a pull request to optimize it?
