Hi All, When I list yum packages on the Redhat/Centos server which is CDH runs, I see some samba packages. Are they necessary or related to some Cloudera services? I have also checked whether there are dependencies on samba but there are no on Linux level. We need to remove or update this package due to CVE-2021-44142. Note: First, We wanted to open a ticket through Cloudera support but it is not possible to open a ticket other than any CDH/CDP component. How can we know more detail about that? Thanks.

Hello, Apache druid cannot be added as a separate service in CDP but I can see its binaries under the CDH-7.1.7 parcel folder. Is Druid available and supported in CDP?

We noticed that this problem occurs only when we enable TLS in Ranger.

You need to install openldap-clients Linux package, which includes ldapsearch tool. yum install openldap-clients You should also pay attention to this documentation while you are enabling the Kerberos. https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/cm_sg_intro_kerb.html#xd_583c10bfdbd326ba--6eed2fb8-14349d04bee--76dd

Hello, we have upgraded our CDH cluster to CDP. After the upgrade, our Sentry policies have been migrated automatically to Ranger. However, Ranger-integrated CDP services cannot interact to get their policies. When I look at the service logs I see some errors which are given below. (Same error in kafka, hdfs, atlas services) Does anyone see this error before? 2:55:00.682 PM ERROR RangerAdminRESTClient
[PolicyRefresher(serviceName=cm_hive)-31]: Failed to get response, Error is : TrustManager is not specified
