------------------------------------------------------------
1、HDFS-16147.002.patch fix the error of test unit at
org.apache.hadoop.hdfs.server.namenode.TestFSImage.testNoParallelSectionsWithCompressionEnabled
2、Upon careful examination, oiv can indeed work normally, and I can't explain
why it works.
3、If I create a parallel compressed image with this patch, and then try to
load it in a NN without this patch and parallel loading disabled, the NN still
able to load it.
It may be hard to understand, but it's true, and you can check it out.
