-------------------------------------
Summary: Possible divide-by-zero exception when closing BatchWriter
Key: ACCUMULO-4420
URL: https://issues.apache.org/jira/browse/ACCUMULO-4420
Project: Accumulo
Issue Type: Bug
Components: core
Affects Versions: 1.7.2, 1.6.5
Reporter: Daniel Blum
Priority: Minor
TabletServerBatchWriter.logStats will throw a divide-by-zero exception if
numBatches is 0 (i.e., no batches have been written).
There are actually no checks for 0 divisors anywhere in the method, so other
such exceptions are possible, as are lesser issues ("Average send rate" and
some other stats come out as NaN when no batches have been written, for
example).
