我想在Elasticsearch批量上传中将请求时间设置为20秒或更长时间.默认时间设置为10秒,我的警告信息天数设置为10.006秒.并且,在显示警告之后,执行正在抛出错误

现在,我想为每个从用户输入的请求或默认设置的任何值设置请求超时.

错误信息:

Neo4j Bolt驱动程序中的Session.run()和transaction.run()有什么区别？

我的知识是:

Session.run() will execute a single statement    
transaction.run() executes multiple statements.

这些是我所知道的正确信息.所有其他差异是什么？

我试图将引号括起来的列表转换为列表.他们是这样做的最佳方式.

Ex: list = "[1,2,3,4,5]"

Operation : Convert list which is string to a list

o/p: list = [1,2,3,4,5]

我正在尝试 Spark 2.x 版本中可用的保存和加载选项。我构建了一个 LogisticRegression 模型并成功保存了模型。但是在加载模型时，面临以下问题

代码片段：

from pyspark.ml.classification import LogisticRegressionModel
LogisticRegressionModel.load("lrmodel")

错误信息：

To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).
