Li Bo commented on HDFS-8704:
-----------------------------
Oh, I see, HDFS-8254 had discussed this problem before its commit. The logic of
client writing is complex and there're many situations that may cause the
writing fail. I think we should fix different situation in different jira, not
all in HDFS-8383.
> Erasure Coding: client fails to write large file when one datanode fails

> I test current code on a 5-node cluster using RS(3,2). When a datanode is
> corrupt, client succeeds to write a file smaller than a block group but fails
> to write a large one. {{TestDFSStripeOutputStreamWithFailure}} only tests
> files smaller than a block group, this jira will add more test situations.
