Hi @vafs , > I think that version is not provided for Cloudera on the CFM right your right, but this platform was the best one so far for all NiFi questions 🤙 I will update this thread, if i got a solution, either if Cloudera or not

Hi guys, i've just started to work with parquet files, all is running with database own export logics, but they are not traceable - use NiFi was the Idea. Now im just annoyed how bad i am to handle this ... seems no default export available for this, install extensible-bundles ... NoClass here and there etc... Did anybody of you solved to add Parquet to NiFi 2.5.0? I've downloaded and provided nifi-parquet-nar-2.5.0.nar, nifi-hadoop-nar-2.5.0.nar and nifi-hadoop-libraries-nar-2.5.0.nar still NoClassDefFoundErrors in this order of log (single named) - org/apache/nifi/serialization/RecordSetWriterFactory - org/apache/nifi/processors/hadoop/AbstractFetchHDFSRecord - org/apache/nifi/processors/hadoop/AbstractPutHDFSRecord - org/apache/nifi/serialization/RecordReaderFactory - org/apache/nifi/serialization/RecordSetWriterFactory - org/apache/parquet/io/OutputFile - org/apache/parquet/io/InputFile Anybody who can helpt me?

Hi guys, i've got time to check this behaviour! 🤗 Here my changes, which i only made and the AzureAD was requested. nifi@ad62a85cc576:/opt/nifi/nifi-current/conf$ diff nifi.properties nifi.properties.fresh 199c199 < nifi.security.user.oidc.discovery.url=https://login.microsoftonline.com/DirecotoryID/v2.0/.well-known/openid-configuration --- > nifi.security.user.oidc.discovery.url= 202,203c202,203 < nifi.security.user.oidc.client.id=ApplicationID < nifi.security.user.oidc.client.secret=ClientSecret --- > nifi.security.user.oidc.client.id= > nifi.security.user.oidc.client.secret= 205,207c205,207 < nifi.security.user.oidc.additional.scopes=profile < nifi.security.user.oidc.claim.identifying.user=email < nifi.security.user.oidc.fallback.claims.identifying.user=upn --- > nifi.security.user.oidc.additional.scopes=offline_access > nifi.security.user.oidc.claim.identifying.user= > nifi.security.user.oidc.fallback.claims.identifying.user= That was only my first try. I will keep everyone up to date, if i got more infos

Hi, thx for your hints. AzureAD Login is already working, but I will check why after my vacations and keep this topic updated.

mbraunerde · ‎05-23-2023

If nobody got a solution, that's okay, but does anybody got a hint for me to solve the authentication at the rest api of nifi regarding AzureAD OAuth2? *edited - fix typo*

Hi guys, i'm working on a NiFi 1.21.0 and the user login is connected to AzureAd. It's working a nice way for all humans, but we want to check the nifi with our monitoring solution. My login-identity-providers.xml contains <loginIdentityProviders> <provider> <identifier>single-user-provider</identifier> <class>org.apache.nifi.authentication.single.user.SingleUserLoginIdentityProvider</class> <property name="Username">known-user</property> <property name="Password">hashed-known-password</property> </provider> </loginIdentityProviders> My authorizers.xml contains <authorizers> <userGroupProvider> <identifier>file-user-group-provider</identifier> <class>org.apache.nifi.authorization.FileUserGroupProvider</class> <property name="Users File">./conf/users.xml</property> <property name="Legacy Authorized Users File"></property> <property name="Initial User Identity 1"></property> </userGroupProvider> <userGroupProvider> <identifier>aad-user-group-provider</identifier> <class>org.apache.nifi.authorization.azure.AzureGraphUserGroupProvider</class> <property name="Refresh Delay">5 mins</property> <property name="Authority Endpoint">https://login.microsoftonline.com</property> <property name="Directory ID">DirectoryID</property> <property name="Application ID">ApplicationID</property> <property name="Client Secret">ClientSecret</property> <property name="Group Filter Prefix">Nifi-AAD</property> <property name="Page Size">100</property> </userGroupProvider> <userGroupProvider> <identifier>composite-configurable-user-group-provider</identifier> <class>org.apache.nifi.authorization.CompositeConfigurableUserGroupProvider</class> <property name="Configurable User Group Provider">file-user-group-provider</property> <property name="User Group Provider 1">aad-user-group-provider</property> </userGroupProvider> <accessPolicyProvider> <identifier>file-access-policy-provider</identifier> <class>org.apache.nifi.authorization.FileAccessPolicyProvider</class> <property name="User Group Provider">composite-configurable-user-group-provider</property> <property name="Authorizations File">./conf/authorizations.xml</property> <property name="Initial Admin Identity">admin@login-domain.com</property> <property name="Legacy Authorized Users File"></property> <property name="Node Identity 1"></property> </accessPolicyProvider> <authorizer> <identifier>managed-authorizer</identifier> <class>org.apache.nifi.authorization.StandardManagedAuthorizer</class> <property name="Access Policy Provider">file-access-policy-provider</property> </authorizer> <authorizer> <identifier>single-user-authorizer</identifier> <class>org.apache.nifi.authorization.single.user.SingleUserAuthorizer</class> </authorizer> </authorizers> The nifi.properties contains nifi.authorizer.configuration.file=./conf/authorizers.xml nifi.security.user.authorizer=single-user-authorizer nifi.security.allow.anonymous.authentication=false nifi.security.user.saml.authentication.expiration=12 hours nifi.security.user.authorizer=single-user-authorizer nifi.security.user.login.identity.provider=single-user-provider nifi.security.user.jws.key.rotation.period=PT1H nifi.security.user.oidc.discovery.url=https://login.microsoftonline.com/DirecotoryID/v2.0/.well-known/openid-configuration nifi.security.user.oidc.connect.timeout=5 secs nifi.security.user.oidc.read.timeout=5 secs nifi.security.user.oidc.client.id=ApplicationID nifi.security.user.oidc.client.secret=ClientSecret nifi.security.user.oidc.preferred.jwsalgorithm= nifi.security.user.oidc.additional.scopes=profile nifi.security.user.oidc.claim.identifying.user=email nifi.security.user.oidc.fallback.claims.identifying.user=upn My Questions: 1) Is it possible to login with the "known user" of login-identity-providers.xml? 2) How can I access the api? Thank you for your time!

I've created a simple processor on my own => https://github.com/mbraunerDE/nifi-plugins/blob/4cd76e047af88e2ec84f51c883b40f74d1bb9ef0/nifi-mbrauner-plugins-processors/src/main/java/de/mbrauner/nifiplugins/processors/ListSFTPWithInput.java

Hi @SAMSAL , thank you for your help, but you're absoluty right in your second post - the first one seems very "uncomfortable". @MattWho: I really don't care about the content, i've created backup-files in the stages before mailing and only the consumed filenames are relevant for mail. Last time there was 350 files and 35MB for backup 😉

mbraunerde · ‎07-08-2022

Hi guys, i've got a queue containing ~1000 files and i want to receive a mail with all ~1000 filenames. I don't care about the content of all files, only the ${filename} should be put on a list and send as content. Example: - Queue Position 1 - filename: first.xml - Queue Position 2 - filename: second.xml - Queue Position 3 - filename: third.xml Resulting mail content (possibility 1): - first.xml - second.xml - third.xml Resulting mail content (possibility 2): first.xml, second.xml, third.xml Something just like a list of filenames in queue. Dies anybody got an idea how to solve without many api-magic? Greetings and best regards - Max

Hey steven-matison, Thank you for the reply, but I think that way is more complicated to get it supported over multiple versions and easy to understand for my next-year-me.
