Glad to hear it but know that the latest release is 1.3.0 M3. Simply check the official project page [1] and you get all
the info [2], including the download setup from Maven, for both stable and dev/snapshot releases [3]

I think it s better to know how things works from the beginning,so pls would u
like to tell what I have to do (what
should I start with) what should I do to configure elasticsearch (head) with
Hadoop and how can I work with
elasticsearch head
Thank you so much ,really all what u say is so helpful .Thank you

Since you are not specifying the network configuration for an elasticsearch
node, it will default to localhost:9200.
This works as long as you are running Hadoop (Pig, Hive, Cascading, etc...)
on the same machine as Elasticsearch -
based on your exception that is unlikely the case.
Try specifying the `es.nodes` parameter - see the documentation for more
information.
Additionally, you seem to be using the wrong jar of es-hadoop - in your
script you are registering
es-hadoop-1.2.0.jar (which does not support the pig/hive/cascading
functionality) while the stacktrace indicate you
are using es-hadoop-1.3.X.jar.
Make sure you are using es-hadoop-1.3.0.M3.jar (which is released and
available in Maven Central) and no other
version. I recommend starting with the examples in the reference docs,
which show to easily load and store data
to/from Elasticsearch.
Once that works, consider extending your script.
Hope this helps,

STORE weblog_count INTO 'weblogs2/logs2' USING

And what ever I put in the LOAD it gives me the same result,even if I
put the path of me desktop
Thx

Hi,
That isn't a lot of information so it's hard to figure out what's
actually work - one can only guess. Can
you post your
stacktrace/logs and your script pig somewhere - like a gist?
One thing that stands out is that you mention you are using Pig yet
your path points to a Hive warehouse:
> /Failed to read data from "/user/hive/warehouse/books"/
I can infer from this that maybe, the issue, is the fact that you
are trying to read a Hive internal file,
which Pig
can't understand, leading to the error that you see.
Cheers,
