8 years ago ok, so I found this: https://github.com/apache/spark/pull/11443 It seems that spark has migrated the old DataFrame class to Dataset. Might due to my spark version.

Hi, Thanks for your devotion in developing this tool first. My environment: Cloudera CDH 5.6.0+spark 1.5.0 I encountered this error when I tried to generate data using tables.genData():
scala> tables.genData("/hdfs2/ds", "text" ,true ,true,true,true,true) java.lang.NoClassDefFoundError: org/apache/spark/sql/Dataset at java.lang.Class.getDeclaredMethods0(Native Method) at java.lang.Class.privateGetDeclaredMethods(Class.java:2570) at java.lang.Class.getDeclaredMethod(Class.java:2002) at java.io.ObjectStreamClass.getPrivateMethod(ObjectStreamClass.java:1431) ......previously I was just following the README.md, here's what I've done:import com.databricks.spark.sql.perf.tpcds.Tables import com.databricks.spark.sql.perf.tpcds.Tables scala> val tables = new Tables(sqlContext,"/root/tpc-ds/tools" , 50) tables: com.databricks.spark.sql.perf.tpcds.Tables = com.databricks.spark.sql.perf.tpcds.Tables@194765c4I would like to know what is possibly going wrong here? Is it because that I use cloudera distribution of spark or I was using version 1.5.0 which is not supported? Thanks for your help in advance.
