Alex Parvulescu commented on OAK-4883:
--------------------------------------
bq. Before digging further, could you help me understand whether it is expected
that the store.getBlobStore() may return null in some setups
yes, it's expected to have {{null}} when there's no external datastore
configured. When there is one though, the primary will provide a
{{BlobGCMBean}}, but the standby won't, and this is what the current issue is
about: having a {{BlobGCMBean}} on the standby.
> Missing BlobGarbageCollection MBean on standby instance
> -------------------------------------------------------
>
> Key: OAK-4883
> URL: https://issues.apache.org/jira/browse/OAK-4883
> Project: Jackrabbit Oak
> Issue Type: Bug
> Components: segment-tar, segmentmk
> Reporter: Alex Parvulescu
> Assignee: Timothee Maret
> Labels: gc
>
> The {{BlobGarbageCollection}} MBean is no longer available on a standby
> instance, this affects non-shared datastore setups (on a shared datastore
> you'd only need to run blob gc on the primary).
> This change was introduced by OAK-4089 (and backported to 1.4 branch with
> OAK-4093).
