Subject java.lang.NoClassDefFoundError: org/apache/solr/client/solrj/SolrServer
Date Tue, 27 Jun 2017 16:24:37 GMT
I am integrating flume (v 1.7) with solr morphline sinks. Solr version is 6.6.0. But when starting
up flume 
    flume-ng agent --conf conf/ --conf-file conf/agent.conf --name a1 -Dflume.root.logger=INFO,console
> logs/flume.log 

The log file throws NoClassDefFoundError
    java.lang.NoClassDefFoundError: org/apache/solr/client/solrj/SolrServer

But I am sure solr-solrj-6.6.0.jar existed in lib folder

    -rw-rw-r-- 1 jason jason 1.2M Jun 27 15:53 lib/solr-solrj-6.6.0.jar

How can I fix this problem? 

Thanks. 
My morphline conf looks like 
solrLocator: {  collection : collection1  zkHost : "127.0.0.1:2181"}
morphlines : [  {
    id : morphline1    importCommands : ["org.kitesdk.**", "org.apache.solr.**"]
    commands : [      { readJson { } }      { generateUUID { field : id } }     
{ loadSolr: { solrLocator : ${solrLocator} } }    ]  }]
And flume agent conf containing morphline sink (other parts of conf e.g. sources are correctly
configured as it works with different sources and sink such as kafka and s3)
a1.sinks.k1.type = org.apache.flume.sink.solr.morphline.MorphlineSolrSink
a1.sinks.k1.channel = c2a1.sinks.k1.morphlineFile =/path/to/conf/morphline.confa1.sinks.k1.morphlineId
= morphline1
