We had an issue we hive delegation tokens and following suggestion desribed in https://community.cloudera.com/t5/Web-UI-Hue-Beeswax/Potential-misconfiguration-detected-Hue-Hive-Ed... we applied following configuration HS2 and HMS, and to Hive service entirely: <property> <name>hive.cluster.delegation.key.update-interval</name> <value>31536000000</value> </property> <property> <name>hive.cluster.delegation.token.renew-interval</name> <value>31536000000</value> </property> <property> <name>hive.cluster.delegation.token.max-lifetime</name> <value>31536000000</value> </property> <property>
However after restart we see in the logs:
WARN org.apache.hadoop.hive.conf.HiveConf: [main]: HiveConf of name hive.cluster.delegation.key.update-interval does not exist
WARN org.apache.hadoop.hive.conf.HiveConf: [main]: HiveConf of name hive.cluster.delegation.token.max-lifetime does not exist
WARN org.apache.hadoop.hive.conf.HiveConf: [main]: HiveConf of name hive.cluster.delegation.token.renew-interval does not exist
We are using CDH 5.9.3. Is this parameter still supported in this version? I see these constants exist in the code with default values. However, searching for solution in the Internet I found that there is another parameter hive.conf.validation that checks if 'hive.' variables are accepted: https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties
Default Value: true
Added In: Hive 0.10.0 with HIVE-2848
Enables type checking for registered Hive configurations. As of Hive 0.14.0 (HIVE-7211), a configuration name that starts with "hive." is regarded as a Hive system property. With hive.conf.validation true (default), any attempts to set a configuration property that starts with "hive." which is not registered to the Hive system will throw an exception.
Is it our case? Or maybe warnings we see in the logs are misleading and actually hive.cluster.delegation.key.* are updated? But we still see in Hlogs MS messages about new tokens being created/cancelled. I'll be thankful for any clarifications.
