使用 Apache 光束的 ZetaSQL 示例

====我认为这与您的操作系统有关.Beam 是一个统一的框架，但您的异常是从它的依赖项来看的:ZetaSQL 解析器.如果您更改为更新版本的 linux，我认为您的代码片段应该可以工作.I am Facing Issues while Using ZetaSQL in Apache beam Framework (2.17.0-SNAPSHOT). After Going through documentation of the apache beam I am not able to find any sample for ZetaSQL.I tried to add the Planner: options.setPlannerName("org.apache.beam.sdk.extensions.sql.zetasql.ZetaSQLQueryPlanner");But Still Facing Issue, Snippet is added below for help. ``` String sql = "SELECT CAST (1243 as INT64), " + "CAST ('2018-09-15 12:59:59.000000+00' as TIMESTAMP), " + "CAST ('string' as STRING);"; ZetaSQLQueryPlanner zetaSQLQueryPlanner = new ZetaSQLQueryPlanner(); BeamRelNode beamRelNode = zetaSQLQueryPlanner.convertToBeamRel(sql); PCollection<Row> stream = BeamSqlRelUtils.toPCollection(p, beamRelNode); p.run();I Understand we need the below Snippet but failed to create the config Frameworks.newConfigBuilder()and while Running Code I found below Exceptions: Exception in thread "main" java.util.ServiceConfigurationError: com.google.zetasql.ClientChannelProvider: Provider com.google.zetasql.JniChannelProvider could not be instantiated at java.util.ServiceLoader.fail(Unknown Source) at java.util.ServiceLoader.access$100(Unknown Source) at java.util.ServiceLoader$LazyIterator.nextService(Unknown Source) 解决方案 Update: as of 06/23/2020, Beam ZetaSQL is supported on Mac OS as well (not all versions but at least most recent ones)!====I think it is related to your OS. Beam is as unified framework but your exception looks from its dependency: ZetaSQL parser. If you change to a newer version of linux I think your code snippet should work. 这篇关于使用 Apache 光束的 ZetaSQL 示例的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
