Issues creating a graph cluster using Lifecycle Manager (LCM) 

LCM incorrectly configures some necessary information for DSE Graph.

The DataStax Enterprise Help Center also provides troubleshooting information.

Currently, OpsCenter LCM is blocking proper setup and usage of DSE Graph. Some steps can be taken to fix the problems until changes are made in DSE 5.1.3.

The default serializers in dse.yaml file must be updated to match the following for the gremlin_server settings:
gremlin_server:
    maxContentLength: 65536000
    maxChunkSize: 4096000
    port: 8182
    serializers:
      - { className: org.apache.tinkerpop.gremlin.driver.ser.GryoMessageSerializerV1d0, config: { ioRegistries: [org.apache.tinkerpop.gremlin.tinkergraph.structure.TinkerIoRegistry], classResolverSupplier: com.datastax.bdp.graph.impl.tinkerpop.io.DseClassResolverProvider }}
      - { className: org.apache.tinkerpop.gremlin.driver.ser.GryoLiteMessageSerializerV1d0, config: { ioRegistries: [org.apache.tinkerpop.gremlin.tinkergraph.structure.TinkerIoRegistry], classResolverSupplier: com.datastax.bdp.graph.impl.tinkerpop.io.DseClassResolverProvider }}
      - { className: org.apache.tinkerpop.gremlin.driver.ser.GryoMessageSerializerV1d0, config: { serializeResultToString: true }}
      - { className: org.apache.tinkerpop.gremlin.driver.ser.GraphSONMessageSerializerGremlinV1d0, config: { ioRegistries: [org.apache.tinkerpop.gremlin.tinkergraph.structure.TinkerIoRegistry] }}
      - { className: org.apache.tinkerpop.gremlin.driver.ser.GraphSONMessageSerializerV1d0, config: { ioRegistries: [org.apache.tinkerpop.gremlin.tinkergraph.structure.TinkerIoRegistry] }}
    scriptEngines:
      gremlin-groovy:
        config:
          compilerCustomizerProviders:
            "org.apache.tinkerpop.gremlin.groovy.jsr223.customizer.ThreadInterruptCustomizerProvider": []
            "org.apache.tinkerpop.gremlin.groovy.jsr223.customizer.InterpreterModeCustomizerProvider": []
The rpc_address setting must be set to 0.0.0.0 in the dse.yaml file.
LCM does not set the default log level to INFO. Change the setting in the logback-gremlin-server.xml file found in install_location/resources/graph/conf:
<appender name="SYSTEMLOG" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
      <level>INFO</level>
    </filter>
To add the gremlin log reference, insert the following after the SPARK_SERVER_LOGBACK_CONF_FILE reference:
 <include file="${GREMLIN_SERVER_LOGBACK_CONF_FILE}"/>
and the following in the root tag definition after the SparkWorkerFileAppender:
<appender-ref ref="GremlinServerFileAppender" />
The location of the dse.yaml file depends on the type of installation:

Package installations
Installer-Services installations

/etc/dse/dse.yaml

Tarball installations
Installer-No Services installations

install_location/resources/dse/conf/dse.yaml
