Josh Elser commented on ACCUMULO-2464:
--------------------------------------

Looks like HADOOP-10607 would be what we want to use. Still waiting on a patch to be applied to branch-2 which means we'll be waiting for that to be released before we can use it.

> 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).
