Mike Drob created HBASE-19164: --------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
