> Prefetch thread shouldn't run for master store
> ----------------------------------------------
>
> Key: HBASE-28953
> URL: https://issues.apache.org/jira/browse/HBASE-28953
> Project: HBase
> Issue Type: Bug
> Affects Versions: 3.0.0-beta-1, 2.7.0, 2.6.1
> Reporter: Wellington Chevreuil
> Assignee: Wellington Chevreuil
> Priority: Minor
> Labels: pull-request-available
> Fix For: 3.0.0, 2.7.0
>
>
> The master store is hosted on Master processes. Since masters don't have a
> BlockCache, we shouldn't run a prefetch thread at all, when opening the
> master store region.
> Currently, this is causing a NoSuchElementException to be logged in master
> logs, which although harmless, can be confusing for operators:
> {noformat}
