我在当前环境中有一个加密区域hdfs。 我正在使用 Flink 1.2.0 集群使用 Apache Parquet 编写器 1.9.0 版本将 parquet 文件写入 hdfs 加密区域。 我写入非加密区域没有问题，但是当我写入加密区域的那一刻，我遇到了以下错误：
org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.hdfs.UnknownCryptoProtocolVersionException): No crypto protocol versions provided by the client are supported. Client provided: [] NameNode supports: [CryptoProtocolVersion{description='Unknown', version=1, unknownValue=null}, CryptoProtocolVersion{description='Encryption zones', version=2, unknownValue=null}]

我已经阅读了Hadoop版本，并且知道Hadoop TDE(透明数据加密(版本在2.6.0更高版本中发布。 但是 Flink 使用 Hadoop 版本 2.3.0 进行编译。 就 TDE 而言，这会导致任何不兼容问题吗？
你可以下载预构建不同Hadoop版本的Flink，例如2.6.0，或者你可以通过传递-Dhadoop.version=2.6.0来自己构建Flink，选择Hadoop版本给Maven。
