Prefer you use the strategy outlined in HADOOP-17195. Rather than pool settings for each output stream, the store has a single shared pool with semaphores to limit #of active entries per output stream. org.apache.hadoop.util.SemaphoredDelegatingExecutor does this for you. This ensures that when there is a low #of output streams, they good upload performance, but in heavy use then it throttles back. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
