--------------------------------------
[~dragonpic], is there any specific intention behind creating lot of CLONEs?
> CLONE - Erasure Coding: DFSStripedInputStream#seekToNewSource

> Key: HDFS-10080
> URL: https://issues.apache.org/jira/browse/HDFS-10080
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Reporter: dragon
> Assignee: Yi Liu
> Fix For: 3.0.0
>
>
> Ideally, for striped block, an internal block is only on one datanode, so
> {{DFSStripedInputStream#seekToNewSource}} should return *false*, we should
> overwrite {{DFSInputStream#seekToNewSource}} for striped file.
> This patch also remove the hardcode for {{groupSize}}
> {code}
> private final short groupSize = HdfsConstants.NUM_DATA_BLOCKS;
> {code}
