Masatake Iwasaki commented on HDFS-9928:
----------------------------------------
Thanks for the update, [~jojochuang]. The patch looks good to me.
Can you upload the patch for trunk too? I think omitting the part of {{hdfs
namenode -rollingUpgrade}} will make it. (We don't need the part for trunk
since {{downgrade}} option was removed in trunk.)
