> Currently the keyLocation of different versions is stored redundantly in
> OmKeyInfo.
> * OmKeyInfo:
> ** keyLocationVersions: List<OmKeyLocationInfoGroup> stores different
> versions of information in a list.
> * OmKeyLocationInfoGroup:
> ** locationVersionMap: Map<Long, List<OmKeyLocationInfo>> stores different
> versions of location in a map.
> If the versions are large, the redundent location is causing the large GC
> overhead for OM, in our cluster, the OM even crashes because of OOM.
> This ticket is to remove the redundant location information to keep OM
> healthy.
> Attached the OmKeyInfo of a key with 549 versions.
