dse-graph-frames

问题 I have three node dse Cassandra cluster. One node is search enabled, Two node is graph enabled. When I run APIs(which is coded in scala play framework), POST or GET request keeps going and going it does gives a response. There is no any information in logs of Cassandra it is working normally. Earlier i used to use single node cluster where is graph enabled. 回答1: You need to have same workload on all nodes of the same data center, so you need to enable both graph and search on all nodes. 来源：

问题 I have a dse graph in validation/prod environement. The problem occurs when I try to launch a DSEGraphFrame query using Spark in Scala. val graph = spark.dseGraph("my_graph") generates the following exception: Exception in thread "main" com.datastax.driver.core.exceptions.InvalidQueryException: The method DseGraphRpc.getSchemaBlob does not exist. Make sure that the required component for that method is active/enabled at com.datastax.driver.core.exceptions.InvalidQueryException.copy
