Hello Everyone - We have HDP-3.1.0 Installed. Kerberised the cluster. We have enabled Ranger.
We use the same Mysql Database for Ambari/Hive/Ranger. Ambari & Hive works fine, but for Ranger
- we are getting the below error:
Mysql Host 'xx.xx.x.x' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'Connection closed by foreign host.
If I run the "flush Hosts" from mysqldb, Ranger "Test connection" works fine but after a minute or two, it stops connecting.
I followed below the post and made sure all the steps were performed as mentioned:https://community.cloudera.com/t5/Support-Questions/Ranger-Admin-does-not-start/td-p/194424
When I run the "SHOW PROCESSLIST" from Mysql DB, I see connections from Hive and Ambari but nothing from Ranger.
Please let me know if I am missing anything.
