Hi all:  
I want to use ESTap to dump my hadoop data to es,but I came across a  
problem,when I export data to a new index, I  
set es.index.auto.create=yes,so index can be created, and mapping type can  
be created as well, but the type of fields always is string,I want to set  
one field to long,how should I do?  
below is method I haved tried but failed:  
suppose the field name is count and both index and mapping type are uv,I  
have following setting.  
props.setProperty("es.mappings.uv.properties.count.type", "long");

Anyone knows?
