Summary: 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
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}
