    Description

      Recently, our hadoop namenode shutdown when switching active namenode, just because of missing paxos directory. It is created in the default /tmp path and deleted by os for no operation in 7 days. We can avoid this by moving journal directory to a none tmp dir, but it‘s better to make sure namenode works well by a default config.

      The issue throws exception similar to HDFS-10659, also caused by missing paxos directory.
