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? ... View more

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@' ...
