Help with Couchbase connector error
Hi,
I am trying to set a connection to Couchbase. I am at the very beginning,
and I got stuck on this exception
Exception in thread "main" java.lang.UnsupportedClassVersionError:
com/couchbase/spark/StoreMode : Unsupported major.minor version 52.0
Here is the simple code fragment
val sc = new SparkContext(cfg)
val doc1 = JsonDocument.create("doc1",
JsonObject.create().put("some", "content"))
val doc2 = JsonArrayDocument.create("doc2", JsonArray.from("more",
"content", "in", "here"))
val data = sc
.parallelize(Seq(doc1, doc2))
.saveToCouchbase()
}
Any help will be a bless
Thanks!

Het Eyal, I just checked the couchbase spark connector jar. The target
version of some of classes are Java 8 (52.0). You can create a ticket in
https://issues.couchbase.com/projects/SPARKC

StoreMode is from Couchbase connector.
Where did you obtain the connector ?

This implies version mismatch between the JDK used to build your jar and
the one at runtime.
When building, target JDK 1.7
There're plenty of posts on the web for dealing with such error.
Cheers
