Jing Zhao commented on HDFS-8398:
---------------------------------

HDFS-7661 aims to support reading a being written file. So maybe the target version of this
jira should be HDFS-8031?

> Erasure Coding: Correctly calculate last striped block length in DFSStripedInputStream
if it's under construction.

> Currently in DFSStripedInputStream, for continuous block, if it's under construction,
we need to read the block replica length from one of datanode and use it as last block length.
> For striped block, we need to read the length of all internal data blocks of the striped
group, then add them correctly.
