Hi All,
Need opinions / thoughts / best practices.
Has anyone tried integrating Apache Griffin (An open source Data Quality solution for Big Data. More details at http://griffin.apache.org/#about_page) with deployed CDH clusters?
If yes, any documentation available on how to get this done? What are the requirements / prereqs? Any recommendations on best practices? Any additional information or help or documentation (apart from the link shared) shared would be highly beneficial.
Please share your thoughts / feedback / comments.
Thanks

Hello, While browsing through various articles related to Cloudera Manager, I came across an article which talks about exporting Cloudera Manager configs using a script. In this a wget from "${SCM_URL}/cmf/exportCLI" url is doing the trick. Being fairly new with playing APIs, I tried to read across somethings related to CM APIs, however, did not find much. Would be great if someone could help me to understand which exact configurations are exported with the mentioned API. Apologies if seems to be a basic question. However, thought of asking community instead of creating confusions for myself. Thanks snm1523

Thank you for the reply Harsh J. Would you be able to please help me with any quick command / script to identify avoidable open files or files stuck in some process using 'lsof' and guide further actions to take? I tried running a generic 'lsof | grep java' but it obviously gave me a huge list of files and became a bit difficult to get relevant information. Thanks snm1523

Hello All, I am looking for some best practices or recommendations to set a best possible value for rlimit_fds (Maximum Process File Descriptors) property. Currently, it is set to default i.e. 32768 and we are getting File Descriptor Threshold alerts. We would first like to look for a best possible value for rlimit_fds. Is there a formulae or a practice or few checks that can be performed to determine a best value? Thanks snm1523

Hello gzigldrum, Thank you for the guidance. This certainly helps. I will go through both the KB articles you shared and also review the Navigator Server and CM Agent logs for audit health warnings. Will comeback with the findings. In the meantime, any luck with HIVEMETASTORE_CANARY_HEALTH and NODE_MANAGER_WEB_METRIC_COLLECTION? Thanks snm1523

Hello Gzigldrum, Thank you for the reply. Below are the exact health messages from CM for each alert: HIVEMETASTORE_CANARY_HEALTH: The health test result for HIVEMETASTORE_CANARY_HEALTH has become bad: The Hive Metastore canary failed to create a database. OR The health test result for HIVEMETASTORE_CANARY_HEALTH has become bad: The Hive Metastore canary failed to create a partition in the table it created. OR The health test result for HIVEMETASTORE_CANARY_HEALTH has become bad: The Hive Metastore canary failed to drop the table it created. REGION_SERVER_AUDIT_HEALTH: The health test result for REGION_SERVER_AUDIT_HEALTH has become bad: There is a problem processing audits for REGIONSERVER. IMPALAD_QUERY_MONITORING_STATUS: he health test result for IMPALAD_QUERY_MONITORING_STATUS has become bad: There are 1 error(s) seen monitoring executing queries, and 0 errors(s) seen monitoring completed queries for this role in the previous 5 minute(s). Critical threshold: any. HIVESERVER2_SCM_HEALTH: The health test result for HIVESERVER2_SCM_HEALTH has become bad: This role s process is starting. This role is supposed to be started. NAME_NODE_AUDIT_HEALTH: The health test result for NAME_NODE_AUDIT_HEALTH has become bad: There is a problem processing audits for NAMENODE. NODE_MANAGER_WEB_METRIC_COLLECTION: The health test result for NODE_MANAGER_WEB_METRIC_COLLECTION has become bad: The Cloudera Manager Agent is not able to communicate with this role s web server. These health alerts occur in every 2-3 days in a time frame of 2-3 hours creating around 5-10 tickets during each interval. We have also checked from network side to verify if there was a network outage or a glitch in those windows, however, no luck. We have tried to diagnose through logs of each alert, but haven't found anything interesting. Hence, looking for some more guidance on what additional could be checked to identify a root cause of these. Thanks snm1523

Thank you for the quick replies, Gzigldrum. I have created a separate post explaining the alerts we get. Below is the link to the same. Flooded with failed health test alerts For every alert we get an incident in BMC as HP OVO is configured to generate an incident and assign it to us. Every morning we start with close to around 15-20 such incidents followed by 15-20 in rest of the day. Would be great if you could please post some suggestions to troubleshoot those alerts and help in permanently fixing them. Note: I will accept your previous reply as solution to this post. Thanks snm1523
