             Summary: Avoid UUID.randomUUID in tests
                 Key: HBASE-19164
                 URL: https://issues.apache.org/jira/browse/HBASE-19164
             Project: HBase
          Issue Type: Bug
          Components: test
            Reporter: Mike Drob
            Priority: Major


We have a lot of places in our test code where we use {{UUID.randomUUID}} to 
generate table names or paths for uniqueness. Unfortunately, this uses up a 
good chunk of system entropy, since Sun chose that random UUID's should use the 
NativePRNGBlocking implementation.

We don't need to block on entropy for random bits to pick a random table name 
in a test, so we can use something that doesn't strain the system too much - 
secure random can be a source of problems on some VM or containers.
