资源中心

资源中心

如果需要用到资源上传功能，针对单机可以选择本地文件目录作为上传文件夹(此操作不需要部署 Hadoop)。当然也可以选择上传到 Hadoop or MinIO 集群上，此时则需要有Hadoop (2.6+) 或者 MinIO 等相关环境

注意:

如果用到资源上传的功能，那么安装部署中，部署用户需要有这部分的操作权限
如果 Hadoop 集群的 NameNode 配置了 HA 的话，需要开启 HDFS 类型的资源上传，同时需要将 Hadoop 集群下的 core-site.xml 和 hdfs-site.xml 复制到 /opt/dolphinscheduler/conf，非 NameNode HA 跳过次步骤

hdfs资源配置

上传资源文件和udf函数，所有上传的文件和资源都会被存储到hdfs上，所以需要以下配置项：

conf/common.properties  
    # Users who have permission to create directories under the HDFS root path
    hdfs.root.user=hdfs
    # data base dir, resource file will store to this hadoop hdfs path, self configuration, please make sure the directory exists on hdfs and have read write permissions。"/dolphinscheduler" is recommended
    resource.upload.path=/dolphinscheduler
    # resource storage type : HDFS,S3,NONE
    resource.storage.type=HDFS
    # whether kerberos starts
    hadoop.security.authentication.startup.state=false
    # java.security.krb5.conf path
    java.security.krb5.conf.path=/opt/krb5.conf
    # loginUserFromKeytab user
    login.user.keytab.username=hdfs-mycluster@ESZ.COM
    # loginUserFromKeytab path
    login.user.keytab.path=/opt/hdfs.headless.keytab    
    # if resource.storage.type is HDFS，and your Hadoop Cluster NameNode has HA enabled, you need to put core-site.xml and hdfs-site.xml in the installPath/conf directory. In this example, it is placed under /opt/soft/dolphinscheduler/conf, and configure the namenode cluster name; if the NameNode is not HA, modify it to a specific IP or host name.
    # if resource.storage.type is S3，write S3 address，HA，for example ：s3a://dolphinscheduler，
    # Note，s3 be sure to create the root directory /dolphinscheduler
    fs.defaultFS=hdfs://mycluster:8020    
    #resourcemanager ha note this need ips , this empty if single
    yarn.resourcemanager.ha.rm.ids=192.168.xx.xx,192.168.xx.xx    
    # If it is a single resourcemanager, you only need to configure one host name. If it is resourcemanager HA, the default configuration is fine
    yarn.application.status.address=http://xxxx:8088/ws/v1/cluster/apps/%s
