Resolution: Duplicate
> NN failover failed beacuse of lossing paxos directory
> -----------------------------------------------------
>
> Key: HDFS-14424
> URL: https://issues.apache.org/jira/browse/HDFS-14424
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: star
> Assignee: star
> Priority: Major
>
> 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.
