Geoffrey Jacoby commented on PHOENIX-3607:
------------------------------------------
I reopened PHOENIX-3611 and submitted a v3 patch along the lines that
[~apurtell] suggests above, that removes the max size restriction.
> Change hashCode calculation for caching ConnectionQueryServicesImpls
> --------------------------------------------------------------------
>
> Key: PHOENIX-3607
> URL: https://issues.apache.org/jira/browse/PHOENIX-3607
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.8.0, 4.9.0
> Reporter: Geoffrey Jacoby
> Assignee: Geoffrey Jacoby
>
> PhoenixDriver maintains a cache of ConnectionInfo ->
> ConnectionQueryServicesImpl (each of which holds a single HConnection) :
> The hash code of ConnectionInfo in part uses the hash code of its HBase User
> object, which uses the *identity hash* of the Subject allocated at login.
> There are concerns about the stability of this hashcode. When we log out and
> log in after TGT refresh, will we have a new Subject?
> To be defensive, we should do a hash of the string returned by user.getName()
> instead.
