Review request for accumulo and Eric Newton.


handle reseting the writer via AtomicReference.

Bugs: ACCUMULO-2213

Repository: accumulo

Description (updated)

ACCUMULO-2213 Make writer recovery in the Tracer more robust.
    * Cleans up writer reseting in the TraceServer, avoids overly broad catching.
    * tones down log levels in TraceServer to WARN because trace information is transient
and we retry everything.

Diffs (updated)
