hi @Scharan Thanks for the feedback, but we need to configure thread queues for users separately, example: YARN has 1 TB of memory and 400 vCPU we need to configure the following: 1. The default queue occupies 50% (500 GB memory and 200 vCPU) 2. User1 queue occupies 25% (250 GB memory and 100 vCPU) 3. User2 queue occupies 25% (250 GB memory and 100 vCPU) all this configuration must be done in Ambari. how can we make this configuration?

Is it possible to create a dynamic resource pool in YARN on Ambari? We need to limit the use of YARN resources per user.

hi @jromero thanks for the feedback. unfortunately we cannot make the TS logs available as they contain sensitive information. we will try to open a ticket with support. checking the TS replica charts "Total Tablet Size On Disk Across Kudu Replicas", they all contain the same size.

hi @jromero on the page "http://ip_host:8050/rpcz": in "inbound_connections" shows the addresses of other tablet servers with "open" state. in "outbound_connections" it shows the addresses of other tablet servers and master with "open" state. this above also happens with other tablet servers. I didn't find anything that could be related to the mentioned problems.

Hi @jromero the "metrics[1]" and "rpcs[2]" web pages are too long: what should we actually look at? what parameter do we need to look at? [1] - http://ip_host:8050/metrics [2] - http://ip_host:8050/rpcz

hi @jromero kudu is balanced correctly. there are 5 kudu tablet and a total of 1173 replicas and each kudu tablet has 234 tablets, this shows that it is balanced. even being balanced, it presents these two mentioned problems.

We would like to understand two behaviors that Kudu is showing. 1. When restarting the Kudu Tablet, it takes between 5 and 10min for this Kudu Tablet to communicate with the Kudu Master again, why is this happening? 2. There are 5 Kudu Tablets and two of those Kudu Tablets is using more than 90% of the memory that was set in "memory_limit_hard_bytes", why is this happening?

hi @araujo we create server.jsk this way: /usr/lib/jvm/jre/bin/keytool -genkeypair -keystore /opt/cloudera/security/pki_2022_v2/$(hostname -f).jks -keyalg RSA -alias $(hostname -f) -dname "CN=$(hostname -f),OU=Pereira,L=Sao Paulo,ST=Sao Paulo,C=BR" -ext san=dns:$(hostname -f) -ext EKU=serverAuth,clientAuth -validity 730 -storepass 'password22@' -keypass 'password22@' so we create the server.cer like this: /usr/lib/jvm/jre/bin/keytool -export -alias $(hostname -f) -keystore /opt/cloudera/security/pki_2022_v2/$(hostname -f).jks -rfc -file /opt/cloudera/security/pki_2022_v2/$(hostname -f).cer so we import all server.cer from all hosts to jssecacerts file like this: /usr/lib/jvm/jre/bin/keytool -import -file /opt/cloudera/security/pki_2022_v2/server.cer -alias $i -keystore /opt/cloudera/security/pki_2022_v2/jssecacerts -storepass 'password22@'
