>             Project: Hadoop HDFS
>          Issue Type: New Feature
>          Components: journal-node
>    Affects Versions: 3.3.3, 3.3.4
>            Reporter: Ashutosh Gupta

> Add -newEditsOnly option to name node initializeSharedEdits command to format 
> unformatted journal nodes for master replacement.
>  
> The current hadoop has limitations on formatting journal nodes. First, it 
> requires all journal nodes to be present when formatting name node. After 
> that, new journal nodes could not be formatted unless we reformat all of them 
> and destroy all HDFS edit logs.
>  
> $ hdfs namenode -initializeSharedEdits -newEditsOnly
> There are two cases here:
> 1) the replaced master instance has name node running on it, then the above 
> command will only be run once on the existing name node.
> 2) the replaced master instance does not have a name node running on it, then 
> the above command will be run twice. But the above command is idempotent as 
> long as the same command will not be issued at the same time, which could be 
> guaranteed by instance controller when reconfiguring master instances. The 
> reason is that all hadoop name node commands such as format, bootstrap, and 
> initializeSharedEdits are not designed to be thread safe and they rely on an 
> external mechanism, which is a manual work for hadoop admin for on-premise 
> clusters, to make sure that they are not executed concurrently. We still keep 
> the same behavior of the initializeSharedEdits command to minimize the 
> code/logic changes.
