docker安裝hadoop

　　

　　docker爲hadoop的雲化帶來了極大便利,安裝和應用也會更快更方便.進入正題:

docker search hadoop

　　將會看到以下結果:

咱們固然選擇星最多的.選擇第一個:

docker pull sequenceiq/hadoop-docker

而後等待下載.

下載完畢以後啓動docker鏡像:

docker run -it --name hadoop sequenceiq/hadoop-docker /etc/bootstrap.sh -bash

測試運行:

cd $HADOOP_PREFIX
# run the mapreduce
bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-2.7.0.jar grep input output 'dfs[a-z.]+'

# check the output
bin/hdfs dfs -cat output/*

我下載的時候最新的仍是這個2.7版本.後來的小夥伴也不必定是2.7呦.能夠進入share目錄去看一下提供的測試jar包是什麼版本而後運行,而後查看輸出結果
