我有apachenifi独立运行,工作正常。但是,当我试图设置apachenifi来访问hive或hdfs kerberized cloudera hadoop集群时。我有麻烦了。
有人能指导我设置hdfs/hive/hbase(使用kerberos)的文档吗
这是我在nifi.properties中给出的配置
# kerberos #
nifi.kerberos.krb5.file=/etc/krb5.conf
nifi.kerberos.service.principal=pseeram@JUNIPER.COM
nifi.kerberos.keytab.location=/uhome/pseeram/learning/pseeram.keytab
nifi.kerberos.authentication.expiration=10 hours
我引用了各种链接,如,但这些都没有帮助(因为下面的链接说它在nifi0.7.1版本中有问题,所以我尝试了nifi1.1.0版本。我也有同样的痛苦经历)https://community.hortonworks.com/questions/62014/nifi-hive-connection-pool-error.htmlhttpshttp://community.hortonworks.com/articles/4103/hiveserver2-jdbc-connection-url-examples.html
以下是我获取日志时出现的错误:

您在nifi.properties文件中添加的内容对于kerberizing nifi集群非常有用。为了访问kerberized hadoop集群,您需要在nifi的hdfs处理器中提供适当的配置文件和keytab。
例如,如果使用puthdfs写入hadoop群集:
hadoop配置资源:core-site.xml和hdfs-site.xml的路径
kerberos主体:访问hadoop集群的主体
kerberos keytab:使用hadoop集群的krb5.conf生成的keytab的路径。nifi.properties中的nifi.kerberos.krb5.file必须指向相应的krb5.conf文件。
不管nifi是否在kerberized hadoop集群中,这篇文章都可能有用。https://community.hortonworks.com/questions/84659/how-to-use-apache-nifi-on-kerberized-hdp-cluster-n.html
