Konstantin Shvachko commented on HDFS-1623:
-------------------------------------------
# What test plan has been executed for testing this branch implementing HA?
Besides unit tests.
# Have you done any benchmarks, comparing current cluster performance against
the branch? Would be good to have numbers for both cases with HA off and HA on.
