> Project: HBase
> Issue Type: Bug
> Components: Client
> Affects Versions: 0.98.0, 0.96.0
> Reporter: Nicolas Liochon
> Assignee: Nicolas Liochon
> Fix For: 0.98.0, 0.96.1
>
> Attachments: 9987.v1.patch, 9987.v2.patch

>
> Change a Map to a concurrentMap
> Removed the "cachedServer (introduced in HBASE-4785). I suspect that this
> function is not needed anymore as we also have a list of dead servers, and
> accessing the list is not blocking. I will dig into this more however.
> The patch gives a 10% improvement with the NoClusterClient.
