+## Installing with old version hadoop(>=3.1.0)
+
+Although we normally require hive4 to rely on a
+hadoop 3.3.6 cluster environment.
+However, in practice, in an ON YARN environment,
+we can package all the hadoop related dependencies into
+tez&hive so that they do not need to rely on the lib
+of the original hadoop cluster environment at runtime.
+In this way, we can run HIVE4 in a lower version of hadoop,
+provided that the base APIs of the hadoop 3.x series are common to
+each other.
+
+The steps are as follows:
+
+1.Download the high version of the Hadoop package, unzip it, and then set the
hadoop_home finger of the env script in HIVE4 to the path where the high
version of hadoop is unzipped.
+
+2.Compile TEZ to get tez.tar.gz which contains all hadoop related
dependencies,
+first extract it on the physical machine where HIVE is deployed and configure
the TEZ_HOME in HIVE to point to it,
+then place tez.tar.gz in a path in hdfs.

Review Comment:
@deniskuzZ This is just a directory in our production environment; I'm just
illustrating how to install. should i change this to non-snapshot version?

> Currently, many users want to upgrade to HIVE4, but they are often limited by
> the fact that the version of their existing HADOOP cluster is too low to
> upgrade to HIVE4. But in fact, HIVE4 can work with lower versions of
