[jira] [Updated] (HDFS-8704) Erasure Coding: client fails to write large file when one datanode fails

     [ https://issues.apache.org/jira/browse/HDFS-8704?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Li Bo updated HDFS-8704:
------------------------
    Description: 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.
