hadoop - 将数据帧写入 Phoenix

Question

我正在尝试将 Dataframe 写入 Phoenix 表，但出现异常。

这是我的代码:

df.write.format("org.apache.phoenix.spark").mode(SaveMode.Overwrite).options(collection.immutable.Map(
                "zkUrl" -> "localhost:2181/hbase-unsecure",
                "table" -> "TEST")).save();

异常(exception)情况是:

org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in stage 3.0 failed 4 times, most recent failure: 
Lost task 0.3 in stage 3.0 (TID 411, ip-xxxxx-xx-xxx.ap-southeast-1.compute.internal):

我已将 phoenix-spark 和 phoenix-core jar 添加到我的 pom.xml

Answer 1

根据 Phoenix-Spark plugin医生，如果你还没有，你可能想同时设置 spark.executor.extraClassPath和 spark.driver.extraClassPath在SPARK_HOME/conf/spark-defaults.conf包括 phoenix-<version>-client.jar .
