It is a problem for a long time, first of all carefully looked at the details of the operation today: Hadoop Hive + + installation Raiders complete the Spark
But it has been stuck in here:
#启动 Hdfs
$HADOOP_PREFIX/sbin/start-dfs.sh
As Figure: will
node2: starting datanode, logging to /usr/local/hadoop/logs/hadoop-root-datanode-10.211.55.102.out
The line that stuck without moving the knockout round after that
Permission denied (publickey,gssapi-keyex,gssapi-with-mic)
According to this intermediate page ssh use under Linux (based on personal experience summary) The following modifications were made:
(5) ssh login appears: permission denied (publickey.gssapi-with- mic)
Solution:
Modify / etc / ssh / sshd-config file, which will be:
PermitRootLogin NO amended as yes
PubkeyAuthentication yes
plus AuthorizedKeysFile .ssh / authorized_keys front the # masked
PasswordAuthentication no to yes to modify
the final restart sshd service can be! (Service sshd restart)
Still no effect, and finally found the answer here: Help! hdfs not start properly!
Indeed find themselves in this step set a password:
So it has failed to start! After re-operation can finally!
把Hadoop + Hive + Spark 完整安装攻略的内容抄过来担心以后页面会删掉,侵删:
- Prerequisites
桌面环境: Mac OSX
虚拟机管理软体: Vagrant
虚拟机: Virtual Box- Clone repo
git clone https://github.com/bryanyang0528/hellobi
cd hellobi/pyspark/env
- download files
mkdir files
sh download_file.sh
- vagrant up
这边会 up 很久
- 一切正常运行,有红字跳出来也不用怕
- copy ssh key
进入 master 的 root 帐号,把 id_rsa.pub 复制到 authorized_keys 里
接着把 public key 丢给 node
回到 master 后确认连线状况
HADOOP
- Format namenode
hdfs namenode -format
- 启动 Hdfs
$HADOOP_PREFIX/sbin/start-dfs.sh
- 确认
hdfs dfsadmin -report- 启动 Hdfs
$HADOOP_PREFIX/sbin/start-yarn.sh- netstat -nlopt
- 启动集群
/usr/local/spark/sbin/start-all.sh- netstat -nlopt
当出现的结果显示出7077(spark master)和8080(spark UI)两个port被占用的时候,就表示spark成功执行了
/usr/local/spark/sbin/start-all.sh- netstat -nlopt
- pyspark --master spark://10.211.55.100:7077
- 直接敲pyspark启动默认是用本机来执行的,以上是让master来执行
