OpenTSDB 与 kerberized HBase 集成

Question

我想在 OpenTSDB 上做一些 POC。我已经按照安装说明安装了 OpenTSDB，但启动起来很困难。我正在使用启用了 Kerberos 的 HDP 环境，我正在将 OpenTSDB 与 Kerberized HBase 集成，但面临以下异常。如果有人集成了 OpenTSDB 和 Kerberos HBase，请指导..

异常：

Answer 1

您可能会发现 following steps 有用。两个数据库都从 Java 客户端连接到 HBase，尽管 OpenTSDB 中的 Java 客户端可能不同。

Answer 2

我可以使用 OpenTSDB 连接到 kerberos HBase。我列出了我为连接到 kerberos HBase 所做的配置更改。

1) 'opentsdb.conf' 中的配置更改，请确保此文件在您执行运行 tsdb 命令时的路径中。

tsd.network.port = 4242
tsd.storage.hbase.zk_basedir = /hbase-secure
tsd.storage.hbase.zk_quorum = ZKhostname1,ZKhostname2,ZKhostname3
hbase.security.auth.enable=true
hbase.security.authentication=kerberos
hbase.kerberos.regionserver.principal=hbase/hostname@FORSYS.LAN
hbase.sasl.clientconfig=Client

2) 为了避免 classpath/JVM 问题，我已经在位于 '/home/user/opentsdb-2.3.0/build'

的 'tsdb' 文件中完成了所有类路径和 jvm 配置

# Add the src dir so we can find logback.xml 
CLASSPATH="$CLASSPATH:$abs_srcdir/src:/usr/hdp/2.4.2.0-258/zookeeper/lib/:/usr/hdp/2.4.2.0-258/zookeeper/:/etc/hadoop/2.4.2.0-258/0/:/usr/hdp/2.4.2.0-258/hbase/:/etc/hbase/2.4.2.0-258/0/:/home/user/phoenix-4.4.0-HBase-1.1-client.jar"

JVMARGS=${JVMARGS-'-Djava.security.krb5.conf=/etc/krb5.conf -Dhbase.security.authentication=kerberos -Dhbase.kerberos.regionserver.principal=hbase/hostname@FORSYS.LAN -Dhbase.rpc.protection=authentication -Dhbase.sasl.clientconfig=Client -Djava.security.auth.login.config=/home/user/opentsdb-jaas.conf -enableassertions -enablesystemassertions'}

3)opentsdb-jaas.conf 文件

Client {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=false
useTicketCache=true;
}

4) 用于运行 opentsdb tsd 实例的命令，请注意我们可以在命令行覆盖'opentsdb.conf'中配置的一些属性。

./build/tsdb tsd --port=4242 --staticroot=/home/user/opentsdb-2.3.0/build/staticroot --cachedir=/home/user/opentsdb-2.3.0/build/cache-dir --zkquorum=ZKhostname1:2181,ZKhostname2:2181,ZKhostname3:2181
