Devaraj Das commented on HBASE-7851:
------------------------------------
[~stack], the guava dependency comes from a reference to it from
SecureServer.java (look at the stack trace in the jira description). This
problem shouldn't happen on trunk since there is no SecureServer and the RPC
client code-path doesn't reference anything from guava there.
Now coming back to the point on removing guava as a dependency, I wasn't aware
of it. In theory, the patch could have been written to remove the reference to
the guava class in SecureServer.java and instead implement the required
functionality using JDK classes... What do you think?
