We're trying to install CDP 7.1.7 on Isilon with OneFS 8.2.2   We found several documents that we tried to follow:   - https://infohub.delltechnologies.com/section-assets/h18730-dell-emc-powerscale-onefs-cdp-private-base-install-guide - https://dl.dell.com/content/docu92689_PowerScale_OneFS_HDFS_Reference_Guide.pdf?language=en_US&source=Coveo - https://infohub.delltechnologies.com/l/powerscale-onefs-user-mapping-mapping-identities-across-authentication-providers/mapping-rules-cannot-contain-user-principal-name   And more.... We also used the isilon hadoop tools and found a few bugs which we provided Pull Requests for (https://github.com/Isilon/isilon_hadoop_tools/pull/105 & https://github.com/Isilon/isilon_hadoop_tools/pull/106 ) so it seems as if thas hasn't been used in a while.   We were able to finish the basic setup but we do have issues creating the proper User Mapping Rules. The docs say: "You cannot use a user principal name in a user mapping rule. A user principal name (UPN) is an Active Directory domain and username that are combined into an Internet-style name with an @ sign, like an email address: jane@example.com. If you include a UPN in a rule, the mapping service ignores it and might return an error."   Unfortunately, something doesn't quite work. Cloudera Manager automatically created all users in Active Directory for us which means that an impala user could end up having the name "cloudera_xnTfsrendtr" in Active Directory. It does have the correct UPN set ("impala@...") but the UPN can't be used in a mapping.   This means for us that we have to create User Mapping Rules for all users manually which "join" the identities and maps one of those auto-generated users to real ones "cloudera_xnTfsrendtr" -> impala.   That is very cumbersome and the CDP / Isilon install docs don't mention this at all. Are there updated docs anywhere/does anyone have notes on this/done this recently? ... View more
