我们在CDH 5.5群集上使用spark 1.6.1。这项工作在Kerberos上运行良好，但是当我们在静态实现加密时，我们遇到了以下问题： -
Df.write().mode(SaveMode.Append).partitionBy("Partition").parquet(path);
我已经尝试过设置这些值但没有成功： -
sparkContext.hadoopConfiguration().set("parquet.enable.summary-metadata", "true"/"false");
sparkContext.hadoopConfiguration().setInt("parquet.metadata.read.parallelism", 1);
SparkConf.set("spark.sql.parquet.mergeSchema","false");
SparkConf.set("spark.sql.parquet.filterPushdown","true");
理想情况下，我想将summary-metadata设置为false，因为它会在写入期间节省一些时间。

答案 0 :(得分：0)
这似乎是开源Spark 1.6.1和Cloudera的Spark之间的库冲突问题。我更改了我的POM文件以使用
Spark version :- 1.6.0-cdh5.9.1
现在它工作正常。
P.S： - 如果遇到以下错误，可能会将“spark.shuffle.encryption.enabled”设置为true。
