Question

启动spark-sql会话时遇到问题。

最初，当我启动Spark会话时，仅默认数据库可见（Hive的默认数据库不可见，但与Spark相同）。

为了查看配置单元数据库，我将hive-site.xml从hive-conf目录复制到spark-conf目录。复制hive-site.xml之后，出现以下错误。

$ spark-sql

我能够成功运行pyspark和spark-shell会话，并且在pyspark / spark-shell会话中对我可见Hive数据库。

该错误与tez有关，我确认tez服务运行正常。我可以通过hive2成功访问hive表。

我正在使用HDP3.0，并且Hive执行引擎是Tez（Map-Reduce已删除）。

Answer 1

发生此问题的原因是，为了查看spark和Hive3.1蜂巢站点中的数据库，我从/ etc / hive / conf复制了 hive-site.xml 到/ etc / spark / conf中。 xml列出了与 spark-sql 不兼容的新添加属性的详尽列表。

堆栈版本：

HDP3.0

Spark2.3

Hive3.1

因此，将hive-site.xml复制到/ etc / spark / conf后，我从spark /etc/spark/conf/hive-site.xml中删除了以下属性

hive.tez.cartesian-product.enabled 
hive.metastore.warehouse.external.dir 
hive.server2.webui.use.ssl 
hive.heapsize 
hive.server2.webui.port 
hive.materializedview.rewriting.incremental 
hive.server2.webui.cors.allowed.headers 
hive.driver.parallel.compilation 
hive.tez.bucket.pruning 
hive.hook.proto.base-directory 
hive.load.data.owner 
hive.execution.mode 
hive.service.metrics.codahale.reporter.classes 
hive.strict.managed.tables 
hive.create.as.insert.only 
hive.optimize.dynamic.partition.hashjoin 
hive.server2.webui.enable.cors 
hive.metastore.db.type 
hive.txn.strict.locking.mode 
hive.metastore.transactional.event.listeners 
hive.tez.input.generate.consistent.splits

spark-sql：会话启动NoClassDefFoundError中的错误：org / apache / tez / dag / api / SessionNotRunning
