> Project: HBase
> Issue Type: Sub-task
> Components: Client
> Affects Versions: 1.3.0

>
> It seems in HConnectionImplementation#locateRegionInMeta if region location
> is removed from the cache, with large number of client threads we could have
> many of them getting cache miss and doing meta scan, which looks unnecessary
> - we could empty mechanism similar to what we have in IdLock in HFileReader
> to fetch the block to cache, do ensure that if one thread is already looking
> up location for region R1, other threads who need it's location wait until
> first thread finishes his work.
