jpmcmu opened a new pull request #3416: [ZEPPELIN-1070]: Inject Credentials in any Interpreter-Code
URL: https://github.com/apache/zeppelin/pull/3416
 
 
   ### What is this PR for?
   
   This PR is a re-submission of the original ZEPPELIN-1070 PR. The original PR seems to be abandoned and I am currently creating custom builds of Zeppelin with the ZEPPELIN-1070 PR included so I am interested in getting the PR merged. I am submitting two PRs one for 0.8X branch and one that includes fixes for merge conflicts to the master branch.
   
   Original PR Description:
   
   > This PR enables a generic syntax for inserting credentials. A username can be inserted by $[user.entry] where "entry" is the name of the credential. A password can be inserted by $[password.entry].
   > To avoid output of the password all occurences of the password-String in the Interpreter-output will be replaced by "###". This should not be a really secure feature (since the runner of the notebook knows the password anyway), but it should avoid accidential exposure of the used passwords by any sort of interpreter
