Hi @JasmineD,   We might need to consider backing up the following: flow.xml.gz users.xml authorizations.xml All config files in NiFi conf directory NiFi local state from each node NiFi cluster state stored in zookeeper. Please make sure that you have stored the configuration passwords safely. NiFi relies on sensitive.props.key password to decrypt sensitive property values from flow.xml.gz file. If they do not know sensitive props key, they would need to manually clear all encoded values from flow.xml.gz. This action will clear all passwords in all components on the canvas. We need to re-enter all of them once NiFi was recovered. Also, if there are any local files that are required by the DataFlows, that would also need to be backed up as well. (i.e., Custom processor jars, user-built scripts, externally referenced config/jar files used by some processors, etc.).   Note: All the repositories in NiFi are backed up by default. Here is a good article to see how backup works in NiFi. https://community.cloudera.com/t5/Community-Articles/Understanding-how-NiFi-s-Content-Repository-Archiving-works/ta-p/249418   Hope this helps. Please accept the answer and vote up if it did. ... View more

Hi @anshuman  Yes, we have Node labels support in the new CDP. For more details, you can check CDP documentations. https://docs.cloudera.com/ -> Cloudera Data Platform -> Runtime -> Cloudera Runtime  https://docs.cloudera.com/runtime/7.0.2/yarn-allocate-resources/topics/yarn-configuring-node-labels.html   FYI. Cloudera Runtime is the core open-source software distribution within Cloudera Data Platform (CDP) that is maintained, supported, versioned, and packaged as a single entity by Cloudera. Cloudera Runtime includes approximately 50 open source projects that comprise the core distribution of data management tools within CDP, including Cloudera Manager, which is used to configure and monitor clusters managed in CDP. ...

@Suraj Singh Seems it's similar like what we discussed in below thread https://community.hortonworks.com/questions/232093/yarn-jobs-are-getting-stuck-in-accepted-state.html If resubmit jobs will get success ? As discussed earlier this is open bug which fixed in further releases. If you need to apply patch, please involve Hortonworks support. If you are a customer, HWX can release a patch for you if it's technically possible based on specifics of the JIRAs. If you don't have support, you can certainly do it but test it first apply the patch in dev/test and see if it resolves your problem. ... View more

@Michael Bronson After configuration changes, it's safe to restart required services, those restart will make necessary new changes into the system. In our case, yarn.nodemanager.local-dirs will point out to new location /grid/sdb/hadoop/yarn/local instead of old location /var/hadoop/yarn/local . In short, restart will not cause any issue either after delete old files or after change in YARN configuration. I hope this answered your concerns. ... View more
