Brandon,
New JVMs for each slot will be spawned across different jobs. For
tasks of the same job, this shouldn't happen. Are you seeing this
happen for tasks of the same job itself?
Also, since your question may be specific to CDH use, I've moved the
discussion to cdh-u...@cloudera.org (mapreduce
Hello,
I am trying to setup a MapReduce job so that the task JVMs are reused on
each cluster node. Libraries used by my MapReduce job have a significant
initialization time, mainly creating singletons, and it would be nice if
I could make it so that these singletons are only created once per slot,
