Which version of Accumulo are you seeing these files in?
They should be getting cleaned up automatically after
https://issues.apache.org/jira/browse/ACCUMULO-1452 was added to 1.4.5,
1.5.1, and 1.6.0.
The brief explanation of their purpose is that they are the temporary files
for minor/major compactions while the data is still being written and then
they are moved in to place.
