One of our users complained higher latency after application upgrades from
hbase-1.2 client (CDH-5.16.2) to hbase-2.4.5 client with meta replica Load
Balance mode during app restart. I reproduced the regression by a test for meta
lookup.
At my test cluster, there are 160k regions for the test table, so there are
160k entries in meta region. Used one thread to do 1 million meta lookup
against the meta region server.
