升级 Spark 和 Scala 版本后使用 bulkput API 写入 BigTable 时出现问题

Question

我正在使用 JavaHBaseContext bulkput API 写入 BigTable。这适用于以下 spark 和 scala 版本

<spark.version>2.3.4</spark.version>
<scala.version>2.11.8</scala.version>

我们刚刚用Spark 2.4(1.5.23-debian10镜像版本)创建了一个新的dataproc集群我升级了 spark 和 scala 依赖项以使用以下 spark 和 scala 版本并开始出现如下所列的问题。

<spark.version>2.4.7</spark.version>
<scala.version>2.12.10</scala.version>

在我看来它无法实例化 HBaseConnectionCache class 因为它无法找到 scala/Product$class 但是我已经从任何地方排除了 scala-library，现在它只是来自它自己的依赖。任何线索都会有所帮助。

Answer 1

似乎异常与依赖关系有关 org.apache.hbase:hbase-spark:2.0.2.3.1.0.0-78:

java.lang.NoClassDefFoundError: Could not initialize class org.apache.hadoop.hbase.spark.HBaseConnectionCache$ at org.apache.hadoop.hbase.spark.HBaseContext.org$apache$hadoop$hbase$spark$HBaseContext$$hbaseForeachPartition(HBaseContext.scala:488) at org.apache.hadoop.hbase.spark.HBaseContext$$anonfun$bulkPut.apply(HBaseContext.scala:225) at org.apache.hadoop.hbase.spark.HBaseContext$$anonfun$bulkPut.apply(HBaseContext.scala:225)

从 the maven page 可以看出它是使用 Scala 2.11 构建的，这可能解释了它不适用于 Scala 2.12 附带的 Dataproc 1.5。

我认为您可以尝试使用 Spark 2.4 和 Scala 2.11.12 附带的 Dataproc 1.4，并相应地更新您的应用程序的依赖项。
