Question

BigInsights的python版本目前为2.6.6。如何在纱线上运行我的火花作业使用不同版本的Python？

请注意，云上BigInsights的用户没有root访问权限。

Answer 1

安装Anaconda

此脚本在云端4.2企业集群上的BigInsights上安装anaconda python。请注意，这些说明不适用于Basic集群，因为您只能登录shell节点而不能登录任何其他节点。

进入mastermanager节点，然后运行（更改环境的值）：

export BI_USER=snowch
export BI_PASS=changeme
export BI_HOST=bi-hadoop-prod-4118.bi.services.us-south.bluemix.net

接下来运行以下内容。该脚本试图尽可能地具有同等性能，因此如果您多次运行它并不重要：

# abort if the script encounters an error or undeclared variables
set -euo

CLUSTER_NAME=$(curl -s -k -u $BI_USER:$BI_PASS  -X GET https://${BI_HOST}:9443/api/v1/clusters | python -c 'import sys, json; print(json.load(sys.stdin)["items"][0]["Clusters"]["cluster_name"]);')
echo Cluster Name: $CLUSTER_NAME

CLUSTER_HOSTS=$(curl -s -k -u $BI_USER:$BI_PASS  -X GET https://${BI_HOST}:9443/api/v1/clusters/${CLUSTER_NAME}/hosts | python -c 'import sys, json; items = json.load(sys.stdin)["items"]; hosts = [ item["Hosts"]["host_name"] for item in items ]; print(" ".join(hosts));')
echo Cluster Hosts: $CLUSTER_HOSTS

wget -c https://repo.continuum.io/archive/Anaconda2-4.1.1-Linux-x86_64.sh

# Install anaconda if it isn't already installed
[[ -d anaconda2 ]] || bash Anaconda2-4.1.1-Linux-x86_64.sh -b

# You can install your pip modules using something like this:
# ${HOME}/anaconda2/bin/python -c 'import yourlibrary' || ${HOME}/anaconda2/pip install yourlibrary

# Install anaconda on all of the cluster nodes
for CLUSTER_HOST in ${CLUSTER_HOSTS}; 
do 
   if [[ "$CLUSTER_HOST" != "$BI_HOST" ]];
   then
      echo "*** Processing $CLUSTER_HOST ***"
      ssh $BI_USER@$CLUSTER_HOST "wget -q -c https://repo.continuum.io/archive/Anaconda2-4.1.1-Linux-x86_64.sh"
      ssh $BI_USER@$CLUSTER_HOST "[[ -d anaconda2 ]] || bash Anaconda2-4.1.1-Linux-x86_64.sh -b"

      # You can install your pip modules on each node using something like this:
      # ssh $BI_USER@$CLUSTER_HOST "${HOME}/anaconda2/bin/python -c 'import yourlibrary' || ${HOME}/anaconda2/pip install yourlibrary"

      # Set the PYSPARK_PYTHON path on all of the nodes
      ssh $BI_USER@$CLUSTER_HOST "grep '^export PYSPARK_PYTHON=' ~/.bash_profile || echo export PYSPARK_PYTHON=${HOME}/anaconda2/bin/python2.7 >> ~/.bash_profile"
      ssh $BI_USER@$CLUSTER_HOST "sed -i -e 's;^export PYSPARK_PYTHON=.*$;export PYSPARK_PYTHON=${HOME}/anaconda2/bin/python2.7;g' ~/.bash_profile"
      ssh $BI_USER@$CLUSTER_HOST "cat ~/.bash_profile"
   fi
done

echo 'Finished installing'

运行pyspark工作

如果你正在使用pyspark，你可以使用anaconda python，在运行pyspark命令之前设置以下变量：

export SPARK_HOME=/usr/iop/current/spark-client
export HADOOP_CONF_DIR=/usr/iop/current/hadoop-client/conf

# set these to the folders where you installed anaconda
export PYSPARK_PYTHON=/home/biadmin/anaconda2/bin/python2.7
export PYSPARK_DRIVER_PYTHON=/home/biadmin/anaconda2/bin/python2.7

spark-submit --master yarn --deploy-mode client ...

# NOTE: --deploy-mode cluster does not seem to use the PYSPARK_PYTHON setting
...

Zeppelin（可选）

如果您使用的是Zeppelin（as per these instructions for BigInsights on cloud），请在zeppelin_env.sh中设置以下变量：

# set these to the folders where you installed anaconda
export PYSPARK_PYTHON=/home/biadmin/anaconda2/bin/python2.7
export PYSPARK_DRIVER_PYTHON=/home/biadmin/anaconda2/bin/python2.7

我怎样才能使用python＆gt; 2.6.6云企业集群上BigInsights的火花？
