> Normalize RetryingCallable cache clearing and implementations
> -------------------------------------------------------------
>
> Key: HBASE-15678
> URL: https://issues.apache.org/jira/browse/HBASE-15678
> Project: HBase
> Issue Type: Sub-task
> Components: Client
> Reporter: Gary Helmling
> Priority: Major
>
> This is a fair amount of duplication and inconsistency in the meta cache
> handling of RetryingCallable implementations:
> * meta cache is often cleared in prepare() when reload=true, in addition to
> being cleared in throwable()
> * each RetryingCallable implementation does this slightly differently,
> leading to inconsistencies and potential bugs
> * RegionServerCallable and RegionAdminServiceCallable duplicate a lot of
> code, but with small, seemingly unnecessary inconsistencies. We should clean
> these up into a common base with subclasses doing only the necessary
> differentiation.
> The main goal here is to establish some common handling, to the extent
> possible, for the meta cache interactions by the different implementations.
