如何在Spark中将文件保存在HDFS服务器上
这是我的代码'''csv_file.write.mode（'overwrite'）.parquet（'hdfs：/// data / ifckp / docs / csv_files / cs'）'''
这是我的错误：
Py4JJavaError：调用o3621.parquet时发生错误。：org.apache.hadoop.security.AccessControlException：权限被拒绝：user = zeppelin，access = WRITE，inode =“ / docs / csv_files”：jason：hdfs：drwxr-xr-x在org.apache.hadoop.hdfs.server.namenode.FSPermissionChecker.check（FSPermissionChecker.java:399）在org.apache.hadoop.hdfs.server.namenode.FSPermissionChecker.checkPermission（FSPermissionChecker.java:255）在org.apache.ranger.authorization.hadoop.RangerHdfsAuthorizer $ RangerAccessControlEnforcer.checkDefaultEnforcer（RangerHdfsAuthorizer.java:555）在org.apache.ranger.authorization.hadoop.RangerHdfsAuthorizer $ RangerAccessControlEnforcer.checkPermission（RangerHdfsAuthorizer.java:316）在org.apache.hadoop.hdfs.server.namenode.FSPermissionChecker.checkPermission（FSPermissionChecker.java:193）在org.apache.hadoop.hdfs.server.namenode.FSDirectory.checkPermission（FSDirectory.java:1850）在org.apache.hadoop.hdfs.server.namenode.FSDirectory.checkPermission（FSDirectory.java:1834）在org.apache.hadoop.hdfs.server.namenode.FSDirectory.checkAncestorAccess（FSDirectory.java:1793）在org.apache.hadoop.hdfs.server.namenode.FSDirMkdirOp.mkdirs（FSDirMkdirOp.java:59）在org.apache.hadoop.hdfs.server.namenode.FSNamesystem.mkdirs（FSNamesystem.java:3150）在org.apache.hadoop.hdfs.server.namenode.NameNodeRpcServer.mkdirs（NameNodeRpcServer.java:1126）在org.apache.hadoop.hdfs.protocolPB.ClientNamenodeProtocolServerSideTranslatorPB.mkdirs（ClientNamenodeProtocolServerSideTranslatorPB.java:707）在org.apache.hadoop.hdfs.protocol.proto.ClientNamenodeProtocolProtos $ ClientNamenodeProtocol $ 2.callBlockingMethod（ClientNamenodeProtocolProtos.java）在org.apache.hadoop.ipc.ProtobufRpcEngine $ Server $ ProtoBufRpcInvoker.call（ProtobufRpcEngine.java:524）在org.apache.hadoop.ipc.RPC $ Server.call（RPC.java:1025）在org.apache.hadoop.ipc.Server $ RpcCall.run（Server.java:876）在org.apache.hadoop.ipc.Server $ RpcCall.run（Server.java:822）在java.security.AccessController.doPrivileged（本机方法）在javax.security.auth.Subject.doAs（Subject.java:422）在org.apache.hadoop.security.UserGroupInformation.doAs（UserGroupInformation.java:1730）在org.apache.hadoop.ipc.Server $ Handler.run（Server.java:2682）

这是一个简单的权限被拒绝错误。您从作为访问控制工具的游侠得到错误。要求您的hdfs管理员授予您写入要写入的目录或写入另一个目录的权限
