Check your network settings and make sure that the Hadoop nodes can communicate
with the ES nodes.
If you install ES besides Hadoop itself, this shouldn't be a problem.
There are various way to check this - try ping, tracert, etc...
Please refer to your distro manual/documentation for more information about the
configuration and setup.

Hi,
Is your ES instance known by your Hadoop cluster (/etc/hosts) ?
It does not even seems to read in it.
Cheers,
Yann

I installed ES(at the location /usr/lib/elasticsearch/) on our gateway
server and i am able to run some basic
curl commands like XPUT and XGET to create some indices and retrieve
the data in them.
i am able to give single line JSON record but i am unable to give JSON
file as input to curl XPUT .
can anybody give me the syntax for giving JSON file as input for curl
XPUT command?
my next issue is i copied the following 4 elasticsearch-hadoop jar

STORE A into 'usa/ca' USING ESTOR('es.input.json=true');

pig -x mapreduce write_data_to_es.pig
