I met a problem when I use NebulaGraph Database like below：

I want to write offline spark data into NebulaGraph Database by spark-nebula-connector.

But I encountered two problems:

First, the NebulaGraph Database version I use only support spark v2.4 and scala v2.11. For this one, I solve it by downgrading the spark and scala version.

Second, spark connector writes data via client, but clients has strong dependence on guava-14：nebula-java/pom.xml at v3.3.0 · vesoft-inc/nebula-java · GitHub And my spark also has strong dependence on guava，guava-27.0-jre

If I use guava-27.0, it will give java.lang.NoSuchMethodError (com.google.common.net.HostAndPort.getHostText()

If I use guava-14.0, EROOR will be give when the spark reads hive, like Exception in thread “main” java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkArgument

How should I solve this?

Maybe you can refer this solution. Guava-14.0 and Guava-27.0 of the HostAndPort have different methods to acqure hosts. You can change the Guava version in connector or exchange, modify the HostAndPort.getHostTex, and then package it locally.
