Huaxiang Sun commented on HBASE-18070:
--------------------------------------
{quote}So I think what we need to test here, is to write a special test which
will clearRegionLocationCache everytime before issuing the actual read/write
scan request, to simulate bad client behavior. The cluster without this feature
should be dead soon and the cluster with this feature should perform much
better. Of course if you put too many loads then no cluster could be alive, but
we only need to prove that, we can perform better.

[~zhangduo], designing this test is complicated? As Region Server will push
back when it is under load and the client needs to account for how many errors
it run into with meta lookup. Right now, in the PE test, every meta lookup will
go through the meta region (by passing local table cache). We are planning to
increase the meta lookup load and get some testing data. This test is similar
to what you described, what do you think?

> Based on the current doc, memstore replication is not enabled for meta
> replica. Memstore replication will be a good improvement for meta replica.
> Create jira to track this effort (feasibility, design, implementation, etc).
