-------------------------------

             Summary: Fix the editlog corruption exposed by failed TestAddStripedBlocks
                 Key: HDFS-8145
                 URL: https://issues.apache.org/jira/browse/HDFS-8145
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Jing Zhao
            Assignee: Jing Zhao


{{TestAddStripedBlocks}} failed with some editlog corruption. Did some debugging, I can see
at least two issues:
# DFSStripedOutputStream tries to send out an empty packet to close the block even if writing
0 bytes
# Because of the above, NN tries to close the file. This exposes another bug in {{BlockInfoStriped}},
which writes its data/parity block numbers into the close editlog but do not read them while
loading.
