Do atlasClient and tableEntity_us need to be static? I suggest to remove 
static, and mark these as final, as they are initialized only in the 
constructor.

Consider replacing this method with a static constant:
  private static final String[] DSL_QUERIES = new String[] { "from 
DataSet", "from Process" };

tableEntity_us.getTypeName() is the query-string to quickSearch(). Its not 
clear from this usage. I suggest to:
 - remove tableEntity_us as member
 - update quickSearch() with an argument
   public void quickSearch(String searchString) {
 ...
   }

I suggest to remove static for following members:
 - atlasClient
 - dbEntity
 - tableEntityUS
 - ttableEntityCanada
 - loadProcess

- atlasClient can be declared as final, as it is initialized only in the 
constructor
