Description

There are test cases using own clock are failing with TableNotFoundException during region assignment. The reason is the meta scan is not giving any results because of the past timestamps. Need to check in more details. Because of the region assignment failures during create table procedure hbase client wait for 30 mins. So not able to continue running the other tests as well.
