Hi HBase folks,
Does anybody actively use meta replicas in production and take advantage of the
load balanced feature in 2.4?
We’ve verified it in a test cluster and the ITBLL test is dropping lots of
errors.
Client side config:
hbase.locator.meta.replicas.mode = LoadBalance
hbase.meta.replicas.use = true
Server side config:
hbase.meta.replica.count = 3
Error in ITBLL generator run:

Can we say that the feature is broken or I’m missing something.
Thanks,
