Issue with upgrading from 5.5.1 to 6.2.3

Elastic Stack Elasticsearch
1

I recently upgraded the Elasticsearch from 5.5.1 to using ElasticSearch 6.2.3
I get the following error during execution in apache-spark 2.2.1

Exception in thread "main" java.lang.NoClassDefFoundError: org/elasticsearch/common/logging/Loggers
at org.elasticsearch.common.unit.ByteSizeValue.(ByteSizeValue.java:36)
at org.elasticsearch.common.network.NetworkService.(NetworkService.java:56)

at org.elasticsearch.client.transport.TransportClient.(TransportClient.java:273)
at org.elasticsearch.transport.client.PreBuiltTransportClient.(PreBuiltTransportClient.java:128)

It appears that package org.elasticsearch.common.logging; in 6.2.3. is missing the Loggers.class and many others.

Here are the logging dependencies for compiling my application using Elasticsearch 6.2.3 in sbt

                     "org.apache.logging.log4j" % "log4j-api" % "2.9.1",
                     "org.apache.logging.log4j" % "log4j-core" % "2.9.1"
                     "org.elasticsearch" % "elasticsearch" % "6.2.3",
                     "org.elasticsearch.client" % "transport" % "6.2.3"

Any ideas on how to fix this issue? Thanks in advance.

Having the same problem, upgrading from 6.0.0 to 6.2.3. In elasticsearch-6.2.3.jar I can find ByteSizeValue.class however there's no Loggers.class. According to Github Loggers.java exists.

Apparently they moved it out to elasticsearch-core.

I have the same problem, is there any alternative?

You need to use the following dependencies now for 6.2.3 upgrade:
elasticsearch-core-6.2.3.jar
elasticsearch-cli-6.2.3.jar
elasticsearch-6.2.3.jar
elasticsearch-rest-high-level-client-6.2.3.jar
elasticsearch-rest-client-6.2.3.jar

Thanks that worked, there was classpath change to include additional jars mentioned above
