Li Bo commented on HDFS-8704:
-----------------------------
The failure of
{{org.apache.hadoop.hdfs.TestWriteStripedFileWithFailure.testWriteStripedFileWithDNFailure}}
has been fixed by HDFS-8857.
The failure of
{{org.apache.hadoop.hdfs.server.namenode.TestFileTruncate.testTruncateWithDataNodesRestartImmediately}}
seems have no relation with this patch.
> 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.
