----------------------------------
Summary: Running PullServer on a dedicated JVM process which
separates from worker.
Key: TAJO-991
URL: https://issues.apache.org/jira/browse/TAJO-991
Project: Tajo
Issue Type: Sub-task
Reporter: Hyoungjun Kim
Assignee: Hyoungjun Kim
Currently PullServer runs on TajoWorker. If a TajoWorker starts Garbage
Collector, all fetching tasks which run on other worker are paused during
Garbage Collection. Running PullServer on a dedicated JVM process which
separates from worker is helpful avoiding stop the all cluster by GC.
PullServer uses small memory and doesn't share any information and status with
TajoWorker.
