Christopher Tubbs commented on ACCUMULO-3773:
---------------------------------------------

Dropping 1.6.3 from the fixVersion on this. I'm not sure this affects 1.6 at all. The log message described above doesn't exist in 1.6, and the only places I saw it constructed repeatedly that might cause this was in tests and mapreduce, where it would kind of make sense.

> The log message spam is annoying, but I think it's also indicative of a large problem where we are repeatedly re-creating the same ClientConfiguration object over and over again. This is wasteful and unnecessary as the contents of the ClientConfiguration can be static for the lifetime of the server process.
> Need to identify if ClientConfiguration objects are being repeatedly created in the server processes (potentially via AccumuloServerContext) and fix the calling code to avoid the annoying log message over and over.
