Hello Andrés, Yes we had a look at it, in fact it seems it's really solved with 2.7 with https://issues.apache.org/jira/browse/NIFI-14959. I add a look at the code fix provided and well it seems to concern really this partition by attribute. By the way, when we saw this defect, I tried another test. I create a dummy attributs and assign randomly a value 0 - 10 and then tried the partition load by this atrribute. This was even worst than the load balance strategy(I had less reccords processed than the third I had with load balace strategy). If it was the same kind of issue, I was expecting to have roughly the same amount of processed reccords. I say roughly because in this second test I had perhaps 10% of the reccords processed vs 33% with the load balance strategy. In addition, we are not big fans of pushing to our Prod right now a version (2.7.1) which has been released 3 days ago only. That was why we were searching if someone else faced the issue or if someone else was using this version with load balance strategy without having issue. Just to try to narrow down where the issue comes from: nifi 2.4 or our platform. Anyway thank you very much for your answer Andrés, Best regards, Olivier

Hi Matt, What I discovered is that when running nifi on windows 10 ( and possibly linux as well?), any passwords that have special characters like + or \ etc need to be converted to ascii I think it is. so : / becomes %2F + becomes %2B Once i did this, it worked OK.

@JoshuaPreece, welcome to the Cloudera Community! Thank you for reaching out, and it's great to have you here. The error you’re seeing usually indicates that SSO is disabled for your account. Since this requires an internal configuration update, I request that you raise an administrative ticket with Cloudera Support.

@hckorkmaz01 While you are currently still using Apache NiFi 1.x major release version, it has reached end of life and is no longer receiving contributions. As such components will not get library updates or security fixes going forward. Apache NiFi 2.x is currently active major release being contributed to in the community. The PrometheusReportingTask was deprecated in Apache NiFi 1.x and officially removed in Apache NiFi 2.x major release. So I would avoid using it as you will eventually need to move to Apache NiFi 2.x to maintain a secure supported product release. But technically, this reporting task, while not well maintained in the community, is capable of creating a prometheus endpoint which exposes metrics for all components (includes connections) for consumption. That being said, Cloudera has taken steps to create Cloudera versions of many of the deprecated and removed components in Apache NiFi 2.x; as well as, introduced many components not available at all in any Apache release version (PrometheusReportingTask is not one of them that was retained). https://docs.cloudera.com/cfm/4.11.0/nifi-components-cfm/components/ NOTE: You are already using a considerably older Apache NiFI 1.18 release. Many bug fixes and CVEs security issues have been addressed since that release. If you cannot yet move to Apache NiFi 2.x, you should at least be on the most recent release of Apache NIFi 1.28. Please help our community grow. If you found any of the suggestions/solutions provided helped you with solving your issue or answering your question, please take a moment to login and click "Accept as Solution" on one or more of them that helped. Thank you, Matt

@vafsThank you for the detailed information, this fully clarifies the deprecation rationale, possible workarounds, and alternative approaches for gRPC integration in NiFi 2.x!

Thank you very much for trying to help. I’ve been stuck on this subject for the past two weeks, trying to improve queries on Impala. I’m currently on RHEL 9 and have unixODBC installed. I’ve configured my environment via /etc/profile.d/oracle.sh as follows: # Oracle Instant Client configuration export TNS_ADMIN=/opt/oracle/instantclient_12_2/network/admin export PATH=/opt/oracle/instantclient_12_2:$PATH export LD_LIBRARY_PATH=/opt/oracle/instantclient_12_2:/usr/lib64:$LD_LIBRARY_PATH # ODBC configuration export ODBCINI=/etc/odbc.ini export ODBCSYSINI=/etc # Cloudera Impala ODBC configuration export CLOUDERAIMPALAINI=/opt/cloudera/impalaodbc/lib/64/cloudera.impalaodbc.ini I’ve tested with: `isql Impala_KRB14 user password` and it connects successfully, but queries are taking too long. I’m looking for guidance on how to optimize these queries effectively. Here are the version of installed packages: unixODBC 2.3.9 DRIVERS............: /etc/odbcinst.ini SYSTEM DATA SOURCES: /etc/odbc.ini FILE DATA SOURCES..: /etc/ODBCDataSources USER DATA SOURCES..: /etc/odbc.ini SQLULEN Size.......: 8 SQLLEN Size........: 8 SQLSETPOSIROW Size.: 8 rpm -qa | grep cyrus-sasl cyrus-sasl-lib-2.1.27-21.el9.x86_64 cyrus-sasl-gssapi-2.1.27-21.el9.x86_64 cyrus-sasl-plain-2.1.27-21.el9.x86_64 cyrus-sasl-2.1.27-21.el9.x86_64
