@Eduardohahn I would suggest to check the and verify that "Authentication.provider.url" in configuration  is accurate. Then see if you this is accessible via Knox or without it. Based on that you can paste the logs here and get some help.  ... View more

@rok The Threshold value look less here. To avoid getting the reported health alerts we recommend to increase the corresponding configuration values: CM -> Cloudera Management Services -> Configuration -> Search for "Descriptor Fetch Max Tries" CM -> Cloudera Management Services -> Configuration -> Event Server -> Search for "Descriptor Fetch Tries Interval" and change this value for all the roles. We would recommend to increase the "Descriptor Fetch Max Tries" value from the default 5 to 10 in a first step. I after that you are facing the issue than you should look at the agent logs and start from there.  ... View more

@ernesto As per my understanding NO. Since you have removed host and tried re adding which needs a repo with credentials. If you have offline RPMs on other host you can give it a try.  ... View more

@ernesto  What error you are getting? I am not seeing any error description in question.    You should look at agent logs from host and try to hard restart the agent if that help.  https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/cm_ag_agents.html ... View more

@innominate Please refer the below doc that will give you some idea.  Cloudera Manager automatically sets nproc configuration in /etc/security/limits.conf, but this configuration can be overridden by individual files in /etc/security/limits.d/. This can cause problems with Apache Impala and other components. Make sure that the nproc limits are set sufficiently high, such as 65536 or 262144. 1. https://docs.cloudera.com/documentation/enterprise/6/release-notes/topics/rg_os_requirements.html 2. https://docs.cloudera.com/runtime/7.2.9/configuring-hbase/topics/hbase-configure-ulimit-pam-cli.html ...
