Hello,   We have a strange issue here.   We are on CDH 6.3.0 and have sentry in place for authorizations. A user is trying to execute queries from Hue on Impala Editor and fails with Authorization errors. However, same query works fine via Hive and also via Impala shell. It fails only from Hue editor.   We have: 1. Refreshed metadata 2. Invalidated metadata 3. Verified permissions are in place in Sentry 4. There are no logs generated (I checked in Hue, Sentry Server and Catalog server). Please suggest if any other place should also be checked.   Example query: select * from DB.table limit 5;   Kindly help to diagnose and resolve this issue.   Thanks Snm1523 ... View more

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 ... View more

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 ... View more
