             Summary: Log process environment variable on HBase service startup
                 Key: HBASE-9577
                 URL: https://issues.apache.org/jira/browse/HBASE-9577
             Project: HBase
          Issue Type: Improvement
    Affects Versions: 0.94.11, 0.95.2
            Reporter: Aditya Kishore
            Assignee: Aditya Kishore
            Priority: Minor
             Fix For: 0.96.0


HBase services already logs information related to JVM properties and command 
line arguments used to start the services which have been immensely helpful to 
investigate issues.

One thing that they do not log is the environment variables and an unintended 
variable in the environment could lead to a scenario not reproducible anywhere 
else including its original location if the service is restarted differently.

We should log environment variables (excluding those which may contains 
credentials) on service startup with option to disable this logging.
