thank you so much for your quick reply,
Here is what I had done
1-instaled hadoop-1.2.1( pig-0.12.0 / hive-0.11.0 /...)
2-download Elasticsearch-1.0.1 and put it in the same file of hadoop
3-copied the following 4 elasticsearch-hadoop jar files
elasticsearch-hadoop-1.3.0.M2.jar
elasticsearch-hadoop-1.3.0.M2-sources.jar
elasticsearch-hadoop-1.3.0.M2-javadoc.jar
elasticsearch-hadoop-1.3.0.M2-yarn.jar
to /pig and hadoop/lib
4- Add them in the PIG_CLASSPATH
knowing that when I take data from my Desktop and put it in elasticsearch
using pig script it works very well, but when I try to get data from my
HDFS it gives me that :

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.
Cheers,

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

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
