Hi,
I am getting following error on doing contentBuilder = XContentFactory.jsonBuilder().startObject().prettyPrint();

java.lang.NoSuchFieldError: FAIL_ON_SYMBOL_HASH_OVERFLOW
at org.elasticsearch.common.xcontent.json.JsonXContent.(JsonXCon
tent.java:49)
at org.elasticsearch.common.xcontent.XContentFactory.contentBuilder(XCon

tFactory.java:49)

Please help me.

I think that you have conflicting versions of Jackson on your classpath (the dreaded JAR hell). Please ensure that you have the versions of Jackson that Elasticsearch depends on, and that you don't have any conflicting versions.

Man that escalated quickly :smiley:
I also had multiple versions of jackson. Removing older version helped.
