> We can separate TajoPullServer to another Java processor in order to mitigate
> the performance degradation caused by GC. TajoPullServer uses
> {{JAVA_PULLSERVER_HEAP_MAX}} to specify the max heap of TajoPullServer java
> processor. Currently, it is set to 100MB. It is somewhat smaller than usual
> size clusters. This patch changes the HEAP_MAP to 1000MB which seems to be
> proper in usual size clusters.
