Could you change to StringBuilder ?

> Key: TAJO-991
> URL: https://issues.apache.org/jira/browse/TAJO-991
> Project: Tajo
> Issue Type: Sub-task
> Components: data shuffle
> 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.
