I have some question to using elastic search on hive  
I use a hive to join elasticsearch datas , but result value is null!(but  
each table has join key value)

here is my queries,

1. Create table

CREATE EXTERNAL TABLE join\_1 (  
fileownermailguid STRING,  
filecontent STRING  
)  
STORED BY 'org.elasticsearch.hadoop.hive.EsStorageHandler'  
TBLPROPERTIES('es.resource' =  
'smartlap-mi\_filedata\_db-2015-03-27/1721979161', 'es.nodes' =  
'172.19.79.167,172.19.79.168', 'es.port' = '9200')

CREATE EXTERNAL TABLE join\_2 (  
mailguid STRING,  
mailsize INT  
)  
STORED BY 'org.elasticsearch.hadoop.hive.EsStorageHandler'  
TBLPROPERTIES('es.resource' =  
'smartlap-mi\_maildata\_db-2015-03-27/1721979161', 'es.nodes' =  
'172.19.79.167,172.19.79.168', 'es.port' = '9200')

1. Join query  
select a.mailguid, b.filecontent  
from join\_2 a join (select fileownermailguid,filecontent from join\_1) b  
on a.mailguid = b.fileownermailguid

2. select each table  
select a.mailguid, a.mailsize  
from join\_2 a  
where a.mailguid='50CDBC9B-D36B-4272-8AA5-CF3ED5F79039'

select fileownermailguid from join\_1 where  
fileownermailguid='50CDBC9B-D36B-4272-8AA5-CF3ED5F79039'

there is a result appeared in each tables, but, when I use join query,  
there is no result set  
elasticsearch on hive is not work well?

My Es version is 1.4.2, Es-hadoop version is 2.1.0.Beta3 and hive version  
is 0.13.1
