NoClassDefFoundError: org/apache/solr/client/solrj/io/stream/expr/StreamExpressionParameter in Solr and Spark Livy

Question

我正在尝试通过spark 读取存储在Solr 中的数据，但无法显示下面的异常。但是，我在 Livy 配置中传递了以下驱动程序。我试过其他驱动程序版本，但无济于事。我的 Spark 是 2.3.1 版和 Solr 7.4.0.

我已经尝试删除 Solr-solrj.jar，因为 spark-solr 包含它，但也没有成功。

Livy 配置：

  "jars": [
              "hdfs://hdfs-name/utils/jars/solr/solr-solrj-8.6.1.jar",
              "hdfs://hdfs-name/utils/jars/spark-solr-3.8.0.jar"
          ]

Pyspark 代码：

df = spark.read.format('solr').option("zkhost","zk-host:2181").option('collection','collection_name').load()

错误：

An error was encountered:
An error occurred while calling o135.load.

Answer 1

问题解决如下：

我输入了所有运行 Spark 和 hdfs 的服务器，寻找 spark 系统路径中的 solr jar (spark-solr-3.6.0.jar)，作为 jar在 Yarn 的缓存之一（/data/yarn/local/filecache 或 /data/yarn/local/usercache）中，我从所有缓存位置删除了 jar，因此它不再出现在 spark 的系统路径中。在那之后，我只是为 Livy 导入了必要的 jar，它再次工作了。该 jar 看起来已损坏，因此已将其导入 Spark，但库无法正常工作
