【技术实践】kyuubi+集成kerberos认证
分享至：
kyuubi 集成kerberos认证
1.配置
创建kyuubi服务的principal(非必需):
#启动
kadmin.local
#在kadmin命令行增加principal
addprinc -randkey kyuubi/compile.bigdata@BIGDATA
WARNING: no policy specified for kyuubi/compile.bigdata@BIGDATA; defaulting to no policy
Principal "kyuubi/compile.bigdata@BIGDATA" created.
#导出keytab
xst -k /etc/security/keytabs/kyuubi.keytab kyuubi/compile.bigdata@BIGDATA
#检查keytab文件
klist -kt /etc/security/keytabs/kyuubi.keytab
Keytab name: FILE:/etc/security/keytabs/kyuubi.keytab
KVNO Timestamp Principal
---- ------------------- ------------------------------------------------------

2 11/15/2018 11:21:00 kyuubi/compile.bigdata@BIGDATA
2 11/15/2018 11:21:00 kyuubi/compile.bigdata@BIGDATA
2 11/15/2018 11:21:00 kyuubi/compile.bigdata@BIGDATA
2 11/15/2018 11:21:00 kyuubi/compile.bigdata@BIGDATA
2 11/15/2018 11:21:00 kyuubi/compile.bigdata@BIGDATA
修改$SPARK_HOME/conf/spark-defaults.conf配置kerberos票据(使用hive)：
spark.yarn.keytab /etc/security/keytabs/hive.service.keytab
spark.yarn.principal hive/compile.bigdata@BIGDATA
spark.yarn.principal – Kerberos principal for Kyuubi server.
spark.yarn.keytab – Keytab for Kyuubi server principal.
修改$SPARK_HOME/conf/spark-defaults.conf配置metastore的keytab(注意：hive.metastore.uris中的主机名要与principal中的HOST一致)：
hive.metastore.warehouse.dir
hive.metastore.kerberos.keytab.file
2.启动
kinit -kt /etc/security/keytabs/hive.service.keytab hive/compile.bigdata@BIGDATA
bin/start-kyuubi.sh --driver-memory 1g --conf spark.kyuubi.backend.session.init.timeout=180s \
--conf spark.driver.extraClassPath=$JARS \
--conf spark.executor.extraClassPath=$JARS \
--conf spark.driver.allowMultipleContexts=true \
--conf spark.kyuubi.authentication=KERBEROS \
--deploy-mode client
3.客户端连接
kinit -kt /etc/security/keytabs/hive.service.keytab hive/compile.bigdata@BIGDATA
bin/beeline -u "jdbc:hive2://compile.bigdata:10009/;principal=hive/compile.bigdata@BIGDATA"
新建用户：
addprinc -randkey jiadx/compile.bigdata@BIGDATA
xst -k /etc/security/keytabs/jiadx.keytab jiadx/compile.bigdata@BIGDATA
使用该用户连接：
#使用jiadx初始化票据
kinit -kt /etc/security/keytabs/jiadx.keytab jiadx/compile.bigdata@BIGDATA
#仍然需要用hive principal连接jdbc
bin/beeline –u
"jdbc:hive2://compile.bigdata:10009/;principal=hive/compile.bigdata@BIGDATA"
#查看当前已初始化票据的用户：
0: jdbc:hive2://compile.bigdata:10009/> select current_user(); #hive中的命令
+--------+--+
| _c0 |
+--------+--+
| jiadx |
+--------+--+
1 row selected (0.992 seconds)
#也可以hive.server2.proxy.user=hdfs 参数设置用户
bin/beeline –u
"jdbc:hive2://compile.bigdata:10009/;principal=hive/compile.bigdata@BIGDATA;hive.server2.proxy.user=hdfs"
0: jdbc:hive2://compile.bigdata:10009/> select current_user();
+-------+--+
| _c0 |
+-------+--+
| hdfs |
+-------+--+
1 row selected (0.675 seconds)
如果使用jiadx principal连接会有错误：
bin/beeline -u "jdbc:hive2://compile.bigdata:10009/;principal=jiadx/compile.bigdata@BIGDATA;auth=kerberos"
