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')
2. Join query
select a.mailguid, b.filecontent
from join_2 a join (select fileownermailguid,filecontent from join_1) b
on a.mailguid = b.fileownermailguid
3. 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
