Hello All, I have a few questions concerning the TaskTracker's JVM re-use that I couldn't unearth some details about:
Is the configured amount of tasks for reuse a suggestion or will it actually use it? For example, if I've configured it to use a JVM for 4 tasks, will a TaskTracker that has 8 tasks to process use 2 JVMs? Or does it decide if it actually wants to reuse one up to the maximum configured number? Will a TaskTracker use the same JVM for tasks from different jobs? Related to this, will a TaskTracker idle a JVM until it has enough tasks to fit the maximum JVM reuse variable? Thanks, Adam
