+## Background
+### What is hadoop-client docker image and why we need this?
+As we all know, the node you want to deploy Kylin, should has provided Hadoop
+dependency(jars and configuration files), these dependency let you have access
+ to Hadoop Service, such as HDFS, HBase, Hive, which are needed by Apache
Kylin.
+Unfortunately, each Hadoop distribution(CHD or HDP etc.) has its own specific
jars. So, we
+can provided specific image for specific Hadoop distribution, which will make
image management task
+more easier. This will have following two benefits:
+1. Someone who has better knowledge on Hadoop can do this work, and let kylin
+ user build their Kylin image base on provided Hadoop-Client image.
+2. Upgrade Kylin will be much easier.
+
+### Build Step for CDH5.7
+1. Place Spark binary(*spark-2.3.2-bin-hadoop2.7.tgz*) into dir
`provided-binary`.
+2. Run `build-image.sh` to build image.
+
+> If you are using other hadoop distribution, please consider build image
yourself.
