iwasakims commented on issue #584: BIGTOP-3293. Add hadoop-kms package. URL: https://github.com/apache/bigtop/pull/584#issuecomment-579353433 I manually tested that hadoop-kms service starts and `hadoop key` works after `sudo yum install hadoop-kms`. Keystore password must set set before starting hadoop-kms service. You may need to set JAVA_OPTS to make Tomcat bind ipv4 address depending on the OS settings. ``` $ sudo bash -c 'echo "export HADOOP_KEYSTORE_PASSWORD=mysecret" >> /etc/hadoop-kms/conf/kms-env.sh' $ sudo bash -c 'echo "export JAVA_OPTS=\"\$JAVA_OPTS -Djava.net.preferIPv4Stack=true -Djava.net.preferIPv4Addresses=true \"" >> /etc/hadoop-kms/conf/kms-env.sh' $ sudo service hadoop-kms start ``` Client-side settings must be set in /etc/hadoop/conf/core-site.xml. ``` <property> <name>hadoop.security.key.provider.path</name> <value>kms://http@localhost:16000/kms</value> </property> ```
