Question

我开始学习Solr，并且尝试使用Solr和Spark编写WordCount示例。但是我有问题，也许与导入或依赖项有关。您可以在下面查看我的代码。

我的依赖项：

class TestView : View("My View") {
    var tf: TextField by singleAssign()

    override val root = BorderPane()

    init {
        with(root) {
            center = form {
                fieldset("Main") {
                    field("File") {
                        vbox {
                            tf = textfield()
                            tf.text("678")
                            tf.clear()
                            tf.text("999")
                        }
                    }
                }
            }
        }
    }
}

我的代码：

<groupId>com.lucidworks.spark</groupId>
<artifactId>spark-solr</artifactId>
<version>2.1.0</version>

<groupId>org.apache.solr</groupId>
<artifactId>solr-solrj</artifactId>
<version>7.6.0</version>

我的问题是object Solr extends SparkApp.RDDProcessor { def getName: String = "query-solr-benchmark" def getOptions: Array[Option] = { Array( Option.builder() .argName("QUERY") .longOpt("query") .hasArg .required(false) .desc("URL encoded Solr query to send to Solr") .build() ) } def run(conf: SparkConf, cli: CommandLine): Int = { val zkHost = cli.getOptionValue("zkHost", "localhost:9983") val collection = cli.getOptionValue("collection", "collection1") val queryStr = cli.getOptionValue("query", "*:*") val rows = cli.getOptionValue("rows", "1000").toInt val splitsPerShard = cli.getOptionValue("splitsPerShard", "3").toInt val splitField = cli.getOptionValue("splitField", "_version_") val sc = new SparkContext(conf) val solrQuery: SolrQuery = new SolrQuery(queryStr) val fields = cli.getOptionValue("fields", "") if (!fields.isEmpty) fields.split(",").foreach(solrQuery.addField) solrQuery.addSort(new SolrQuery.SortClause("id", "asc")) solrQuery.setRows(rows) val solrRDD: SolrRDD = new SolrRDD(zkHost, collection, sc) var startMs: Long = System.currentTimeMillis var count = solrRDD.query(solrQuery).splitField(splitField).splitsPerShard(splitsPerShard).count() var tookMs: Long = System.currentTimeMillis - startMs println(s"\nTook $tookMs ms read $count docs using queryShards with $splitsPerShard splits") // IMPORTANT: reload the collection to flush caches println(s"\nReloading collection $collection to flush caches!\n") val cloudSolrClient = SolrSupport.getCachedCloudClient(zkHost) val req = CollectionAdminRequest.reloadCollection(collection) cloudSolrClient.request(req) startMs = System.currentTimeMillis count = solrRDD.query(solrQuery).count() tookMs = System.currentTimeMillis - startMs println(s"\nTook $tookMs ms read $count docs using queryShards") sc.stop() } }是红色的，我无法运行我的代码。有人知道我错过了吗？

错误：值生成器不是对象org.apache.commons.cli.Option的成员

document.getElementById('my-path').classList.add('green')

我错过了这个依赖。
