Hello,

My SW context : 5 nodes running ES 1.4 + 1 node running ES 1.3

i need to  read node ES 1.4  ( One index + all data indexed) and   write it 
to  nodeES 1.3 .
i have a  java code that do the job but it firstly writes to HDFS and then 
i need a second job
that read  HDFS and send to ES 1.3

i was wondering if iit was possible to do all in one without storing on 
HDFS  
by interfacing both in the same job and  java code 
ES doc mentions  ( but within the same job)  : 

es.resource.read (defaults to es.resource) Elasticsearch resource used for 
reading (but not writing) data. Useful when reading and writing data to 
different Elasticsearch indices within the *same* job. 
es.resource.write

PS: i tried without success the backup/restore possibility from ES

Best R
Phil
