Description

In some cases a task may be scheduled to run on multiple workers. One case where this happens is when running with the Helix task execution framework. Helix may reschedule a task on a different worker if it loses contact with a worker. That worker may continue executing for some time before the task is terminated. During this period if the output file names collide then there may be an error during data publish.

Add an option "writer.addTaskTimestamp" that can be used to reduce the chance of name collisions by appending a task startup timestamp to the file name.
