@felixcheung Yes 2.2, Maybe it's because my maven repo has different
versions of hadoop libraries like following.
```
~/zeppelin$ ls -al ~/.m2/repository/org/apache/hadoop/hadoop-common/
total 36
drwxrwxr-x 9 hsshim hsshim 4096 8ì 16 17:03 .
drwxrwxr-x 25 hsshim hsshim 4096 8ì 17 00:22 ..
drwxrwxr-x 2 hsshim hsshim 4096 8ì 16 17:04 2.2.0
drwxrwxr-x 2 hsshim hsshim 4096 6ì 22 12:04 2.3.0
drwxrwxr-x 2 hsshim hsshim 4096 6ì 22 00:07 2.4.0
drwxrwxr-x 2 hsshim hsshim 4096 6ì 22 00:14 2.5.1
drwxrwxr-x 2 hsshim hsshim 4096 8ì 4 19:54 2.6.0
drwxrwxr-x 2 hsshim hsshim 4096 8ì 16 14:50 2.7.0
drwxrwxr-x 2 hsshim hsshim 4096 7ì 14 16:58 2.7.2
```
