Does the current library support spark 2.1.1 .
The code is breaking for me . Printschema works fine , but show and collect breaks.
Could you link the logs/stacktraces that you are seeing? Have you upgraded from a previous version or is this a fresh install?
James
I did fresh installation of Spark 2.1.1 and installed ELK 5.4 and EShadoop
5.4. Previuous version I had issues with reading child array into dataframe
. I can printschema but but select crashes.
Have upgrade to the lastest version of spark and elk i am unable to run
basic select from dataframe. please refer below stack.

Which version of Scala are you running Spark on top of and which specific version of ES-Hadoop are you using? Generally seeing java.lang.NoClassDefFoundError: scala/collection/GenTraversableOnce$class means that you are mismatching scala versions 2.10 and 2.11.
We are using pyspark for coding and have Scala version 2.11.8
Do we have any update ?
Sorry for disappearing there. This error almost always means that you are using the incorrect version of ES-Hadoop for your version of Scala. Do you have the artifact name for elasticsearch-spark that you are using? It should end in _2.11
My Bad was using wrong version . Do you have any working example of
exploding nested json stored in elastic , will appreciate your help.
I have the same problem, my Scala version and elasticsearch-spark are both in 2.11.
I can successfully insert data to elasticsearch, but I can't read data from elasticsearch.
(with Elastic Stack 5.4.0 and Spark 2.1.1)
My code:
val es_df = sqc.read.format("org.elasticsearch.spark.sql").load("test/daily_player_game")

Yes. There is only one node in my elk cluster and it's a new server which does not have any old version jars before.
