cloudera - 无法在 Cloudera Quickstart VM 中安装 Spark 2.2 (5.10)

Question

我已经关注了这里的博客(如下所述)并下载了包裹并按照要求放置。请告诉我是否有人已安装以及步骤。

(https://www.cloudera.com/documentation/spark2/latest/topics/spark2_installing.html)

/opt/cloudera/csd/SPARK2-2.1.0.cloudera2-1.cdh5.7.0.p0.171658-el5.parcel

但是服务cloudera-scm-server restart没有执行。要使用 Cloudera Express(免费)，请运行:

sudo /home/cloudera/cloudera-manager --express

这需要至少 8 GB RAM 和至少 2 个虚拟 CPU。

SPARK 2.2 Installation Setup on Cloudera VM

Step 1: Download a quickstart_vm from the link:
Prefer a vmware platform as it is easy to use, anyways all the options are viable.
Size is around 5.4gb of the entire tar file. We need to provide the business email id as it won’t accept personal email ids. 


Step 2: The virtual environment requires around 8gb of RAM, please allocate sufficient memory to avoid performance glitches.


Step 3: Please open the terminal and switch to root user as:
         su root
         password: cloudera

Step 4: Cloudera provides java –version 1.7.0_67 which is old and does not match with our needs. To avoid java related exceptions, please install java with the following commands:
(a). Downloading Java:
wget -c --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-linux-x64.tar.gz

(b). Switch to /usr/java/ directory with “cd /usr/java/” command.

(c). cp the java download tar file to the /usr/java/ directory.

(d). Untar the directory with “tar –zxvf jdk-8u31-linux-x64.tar.gz”

(e). Open the profile file with the command “vi ~/.bash_profile” 

(f). export JAVA_HOME to the new java directory.
       “export JAVA_HOME=/usr/java/jdk1.8.0_131”

       Save and Exit.


(g). In order to reflect the above change, following command needs to be executed on the shell:
       source ~/.bash_profile

Step 5:  The Cloudera VM provides spark 1.6 version by default. However, 1.6 API’s are old and do not match with production environments. In that case, we need to download and manually install Spark 2.2.

(a). Switch to /opt/  directory with the command:
“cd /opt/”

(b). Download spark with the command:
wget https://d3kbcqa49mib13.cloudfront.net/spark-2.2.0-bin-hadoop2.7.tgz

(c). Untar the spark tar with the following command:
tar -zxvf spark-2.2.0-bin-hadoop2.7.tgz

(d). We need to define some environment variables as default settings:
Please open a file with the following command:
vi /opt/spark-2.2.0-bin-hadoop2.7/conf/spark-env.sh
Paste the following configurations in the file:
SPARK_MASTER_IP=192.168.50.1
SPARK_EXECUTOR_MEMORY=512m
SPARK_DRIVER_MEMORY=512m
SPARK_WORKER_MEMORY=512m
SPARK_DAEMON_MEMORY=512m
Save and exit

(e).    We need to start spark with the following command:
/opt/spark-2.2.0-bin-hadoop2.7/sbin/start-all.sh
Export spark_home : 
export SPARK_HOME=/opt/spark-2.2.0-bin-hadoop2.7/

(f). Change the permissions of the directory:
chmod 777 -R /tmp/hive

(g). Try “spark-shell”, it should work.
