Hello. Before deleting rows in a specific table (463,462 rows in table), HDFS file size is : $ hadoop fs -du -s -h /apps/hive/warehouse/prd_thmil.db/th_mil_fb_code_value_brut 54.2 M 162.6 M /apps/hive/warehouse/prd_thmil.db/th_mil_fb_code_value_brut 54.2 Mb is the size of 1 file and each file is replicated 2 times so 162.6 Mb is the total size, it OK.

Hello. We are running Cloudera CDP 7.1.7 and Cloudera Manager 7.4.4 but when we access Hue UI we can only browse Jobs : Do we have to follow links given in the article ? https://docs.cloudera.com/cdp-private-cloud-base/7.1.8/hue-introduction/topics/hue-about-query-processor.html Is it for CDP 7.1.8 and higher ?

Hello. In Yarn Queue Manager, there is 4 queues defined : but when we submit queries (using Hue or SAS Software to load data), only the default queue is used. And we can go very high : From what we undestand, Default queue is defined for using 20% of the cluster but can use up to 100%, so 70% is normal. But our cluster is 365 GB / 15 vCores and some applications can use more : 7 / 7 / 6 / 5 / 3 vCores in the graph = 28 vCore ! How is it possible ? Thanks for your help   ... View more
