Kerberized Hadoop ClusterにApache NiFiを設定する方法

Question

私はApache NiFiをスタンドアロンで動作させています。しかし、私がに設定しようとすると、Apache NiFiがハイブまたはHDFSにアクセスするようになります。 Kerberized Cloudera Hadoop Cluster。私は問題を抱えています。

誰かがここで（ケルベロスで）HDFS /ハイブ/ HBaseの設定については、ドキュメントに

私を導くことができる、私はnifi.properties

# 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 

に与えた構成です私は好きなような様々なリンクを参照しましたが、それらのどれも役に立ちません。 は（下記リンクは、それがNiFi 0.7.1バージョンに問題があったので、私は同じ苦い経験を​​しましたNiFi 1.1.0バージョンを試してみました） はここhttps://community.hortonworks.com/questions/62014/nifi-hive-connection-pool-error.html https://community.hortonworks.com/articles/4103/hiveserver2-jdbc-connection-url-examples.html

は、私は、ログを取得していますエラーです：

Answer 1

nifi.propertiesファイルで追加した内容は、nifiクラスタのKerberos化に役立ちます。 kerberized hadoopクラスタにアクセスするには、NiFiのHDFSプロセッサに適切な設定ファイルとキータブを用意する必要があります。例えば

、あなたはHadoopクラスタへの書き込みをputHDFSを使用している場合：

Hadoopの設定リソース：あなたの校長へ：コア-site.xmlのとHDFS-site.xmlの

Kerberos主体へのパスアクセスhadoopクラスタ

kerberos keytab：hadoopクラスタのkrb5.confを使用して生成されたkeytabへのパス。 nifi.propertiesのnifi.kerberos.krb5.fileは、適切なkrb5.confファイルを指さなければなりません。

NiFiがケルベロイドハープクラスターの内部にあるかどうかにかかわらず、この投稿は役に立つかもしれません。 https://community.hortonworks.com/questions/84659/how-to-use-apache-nifi-on-kerberized-hdp-cluster-n.html
