isEmpty=$(hdfs dfs -count /some/path | awk '{print $2}')
if [[ $isEmpty -eq 0 ]];then
    echo "Given Path is empty"
    #Do some operation
else
    echo "Given Path is not empty"
    #Do some operation
fi

count: 

hdfs dfs -count /path
           1            0                  0 /path

The output columns are: DIR_COUNT, FILE_COUNT, CONTENT_SIZE, PATHNAME

du: 

hdfs dfs -du -s /path
0  /path

If there are 0 byte files or empty directories, the result would still be 0.
