> If you have a large number of files in HDFS, the fsimage file is very big.
> When the namenode restarts, it writes a copy of the fsimage to all
> directories configured in fs.name.dir. This takes a long time, especially if
> there are many directories in fs.name.dir. Make the NN write the fsimage to
> all these directories in parallel.
