[hadoop] Pipelining Hadoop/Spark with ElasticSearch

Hi,

I'm trying to write hadoop aggregation results to ES.
Say I've K, V for key and value classes respectively. According to
elasticsearch-hadoop api/blog, the key is ignored and the value should be a
Map<K, V>.
I'm a little bit confused here: do I need an extra map job to convert my
(K, V) to (Null, Map<K, V>) ?
Is there any complete examples of using hadoop and ES together?

Thanks.

Have you tried the elasticsearch-hadoop plugin? There is good
documentation on the website.

Hi,

I replied on IRC but you left. See the docs here [1]. The value represents your document and since it might contain
multiple fields, ESOuputFormat expects a Map (MapWritable) which contains the actual document. Say your doc is something
like { foo: 123 } then your map would be [Text("foo"):new LongWritable(123)].

The docs provides more information about the Writable types supported (basically all of them) and their equivalent ES types.

Thanks. Seems like I misunderstand something.

Now I managed to push documents to ES, and I'd like to know if these are
supported by current version of elasticsearch-binding:

  • specifying id for index. Now the "_id" for the documents pushed are auto
    generated
  • the update api

Thanks.

Hi

Wanted to know if the auto generated id has been committed.

Thanks

Hi

Just wanted to know if the code for changing auto generated id has been
committed or is it yet to be changed? I am using
elasticsearch-spark_2.10.Beta 1 version.

Thanks

One can specify the id for each document for quite some time now, through es.mapping.id parameter [1] - simply point
it to the field containing the ID and you're good to go.
