 ## Installation
 
-Currently you can compile hdfs-utils against Hadoop 3.3.4, 3.3.6, 3.4.0, 3.4.1 or 3.4.2. You need to specify the version by activating either the `hadoop-3.3.4`, `hadoop-3.3.6`, `hadoop-3.4.0`, `hadoop-3.4.1` or the `hadoop-3.4.2` profile below.

 The easiest way to achieve this is to put it in the directory `/stackable/hadoop/share/hadoop/tools/lib/`.
 The Stackable HDFS already takes care of this, you don't need to do anything in this case.
