Caused by: java.io.IOException: error=2, No such file or directory error in Colab Hadoop - hadoop

Question

I'm Hadoop in Colab and I have two documents that I've made in Pycharm, one with the mapper and another one with the reducer part.
This is the code:
!apt-get install -y openjdk-11-jdk-headless -qq > /dev/null
!wget https://downloads.apache.org/hadoop/common/hadoop-3.3.3/hadoop-3.3.3.tar.gz
!tar -xzf hadoop-3.3.3.tar.gz
!mv hadoop-3.3.3/ /usr/local/
import os
os.environ["JAVA_HOME"] = "/usr/lib/jvm/java-11-openjdk-amd64"
os.environ["HADOOP_HOME"] = "/usr/local/hadoop-3.3.3"
os.environ["PATH"] += os.pathsep + "/usr/local/hadoop-3.3.3/bin"
!chmod u+x ./mapperModaGastoPorPersona.py
!chmod u+x ./reducerModaGastoPorPersona.py
!hadoop jar $HADOOP_HOME/share/hadoop/tools/lib/hadoop-streaming-3.3.3.jar -file ./mapperModaGastoPorPersona.py -mapper ./mapperModaGastoPorPersona.py -file ./reducerModaGastoPorPersona.py -reducer ./reducerModaGastoPorPersona.py -input Datos_actividad_1.txt -output ./salidaModaGastoPersona1
And the result in the last part is this:

I've uploaded the documents "mapperModaGastoPorPersona.py", "reducerModaGastoPorPersona.py" and "Datos_actividad_1.txt" in Colab.
