------------------------------------

             Summary: Trace user password required in plaintext in accumulo-site.xml
                 Key: ACCUMULO-2464
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2464
             Project: Accumulo
          Issue Type: Improvement
          Components: trace
    Affects Versions: 1.5.1
            Reporter: Josh Elser
            Assignee: Josh Elser
             Fix For: 1.5.2, 1.6.1


The {{trace.password}} property is used by the Tracer to authenticate with Accumulo and persist the traces in the trace table. Presently, this is required to be in plaintext which is rather sub-par, but has been overlooked mostly because that password is for an isolated user account which shouldn't have access to any sensitive data.

I'm thinking of the following: provide some new storage in ZK akin to the acl + salt that's currently done for the passwd db and instance.secret (with a new secret for this, of course)

Another option might be to provide a hashing command that will hash the password, store that instead of the plaintext, and then use the hash with a salt to authenticate (not exposing the hash-authentication method to users). Not sure how I feel about that.

Leveraging some BCrypt library might be nice too (if there's an ASF license compatible lib somewhere).
