--------------------------------
Hello [~mhthanh],
You are right. we should update the documents.
Pullserver use the os cache in hadoop native. unfortunately hadoop codes was
updated frequently.
we need to specifying version for a while. and I will fix that if tajo binary
is without specific version, this functions to be disabled.
> Running PullServer on a dedicated JVM process which separates from worker.

> 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.
