我正在尝试将对象转换为 org.apache.hadoop.hbase.client.Put 在 DoFn 中。我不断收到此错误:

但是,如果我使用与 org.apache.hadoop.hbase.client.Put (任何自定义类型)不同的类,则不会发生错误

如您所见,输出后没有对 Put 对象进行任何修改。

这是我使用的库

compile group:'com.google.cloud.dataflow', name:'google-cloud-dataflow-java-sdk-all', version:'1.7.0'
compile group:'com.google.cloud.bigtable', name:'bigtable-hbase-dataflow', version:'0.9.2'

任何的想法 ?

很抱歉给您带来麻烦。这是云 Bigtable 连接器中的一个错误。我们为即将发布的 0.9.3 版本修复了此问题。

您有两种选择来解决此问题:

  1. 升级到 0.9.3-SNAPSHOT。您将需要此 pom.xml中的存储库部分。在正式发布 0.9.3 版本之前,我们正在等待另一个修复的确认。这应该有望在下周初发生。
  2. Put.addColumn()使用 0.9.2 并在所有调用中设置时间戳参数 (System.currentTimeMillis()) 。
