(Updated Jan. 21, 2014, 8:12 p.m.)


Review request for accumulo and Eric Newton.


Changes
-------

after conversation with mdrob, pulled the TSBW log additions, because they're too specific
to ACCUMULO-2213 to be generally useful.


Bugs: ACCUMULO-2213
    https://issues.apache.org/jira/browse/ACCUMULO-2213


Repository: accumulo


Description
-------

ACCUMULO-2213 Make writer recovery in the Tracer more robust.
    
    * Adds optional logging to TSBW closure so we can better instrument long run tests to
look for problems.
    * 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)
