> refactor and improve decommissioning logic
> ------------------------------------------
>
> Key: HBASE-22254
> URL: https://issues.apache.org/jira/browse/HBASE-22254
> Project: HBase
> Issue Type: Improvement
> Reporter: Sergey Shelukhin
> Assignee: Sergey Shelukhin
> Priority: Major
> Attachments: HBASE-22254.01.patch, HBASE-22254.patch
>
>
> Making some changes needed to support better decommissioning on large
> clusters and with container mode; to test those and add clarify I moved parts
> of decommissioning logic from HMaster, Draining tracker, and ServerManager
> into a separate class.
> Features added/improvements:
> 1) More resilient off-loading; right now off-loading fails for a subset of
> regions in case of a single region failure; is never done on master restart,
> etc.
> 2) Option to kill RS after off-loading (good for container mode HBase, e.g.
> on YARN).
> 3) Option to specify machine names only to decommission, for the API to be
> usable for an external system that doesn't care about HBase server names, or
> e.g. multiple RS in containers on the same node.
> 4) Option to replace existing decommissioning list instead of adding to it
> (the same; to avoid additionally remembering what was previously sent to
> HBase).
> 5) Tests, comments ;)
