Scanner creates threads too frequently
--------------------------------------
Key: ACCUMULO-110
URL: https://issues.apache.org/jira/browse/ACCUMULO-110
Project: Accumulo
Issue Type: Bug
Components: client
Reporter: Keith Turner
Assignee: Keith Turner
Fix For: 1.4.0
After the scanner has read a few batches of data from the tablet server it
starts creating read ahead threads to read batches. A thread is created per
batch. After a thread reads a batch it exits. A thread pool was not used
because the scanner does not have a close method. A user suggested using a
static thread pool, see the following email chain.

This static pool should be unbounded, time out threads, use a Synchronous
Queue, and create daemon threads.
