Li Bo commented on HDFS-8838:
-----------------------------
The number of datanodes is set to 9 in the unit test. Due to the problem of
HDFS-8220 or HDFS-8839, I think we should use at least 10 datanodes for testing
one datanode failure.
> Tolerate datanode failures in DFSStripedOutputStream when the data length is
> small
