--------------------------------
Component/s: OM HA
> Need a way to determine relative position of OM instances when cluster is down
> ------------------------------------------------------------------------------
>
> Key: HDDS-1859
> URL: https://issues.apache.org/jira/browse/HDDS-1859
> Project: Hadoop Distributed Data Store
> Issue Type: Sub-task
> Components: HA, OM HA, Ozone Manager
> Reporter: Arpit Agarwal
> Priority: Major
>
> It will be useful to figure out the relative positions of the OM instances
> when the cluster is down.
> In HDFS world, we can do this by examining the edit log files and the
> {{seen_txid}} file.
> In Ozone, this is slightly more difficult. We have to determine
> # relative positions of Ratis logs, i.e. log index and committed index. We
> may need to build some offline Ratis log parser for this.
> # relative positions of state machines. i.e. last applied index.
