**Apache Airflow version**: 1.10.12
**Environment**: docker image running ubuntu 20.04
- **OS** (e.g. from /etc/os-release): Ubuntu 20.04
- **Kernel** (e.g. `uname -a`): 3.10.0-1127.19.1.el7.x86_64
- **Install tools**: installed with pip
**What happened**:
Installed airflow systemwide with user root and the following command :
```
pip install apache-airflow==1.10.12
```
Then creating a user on the system in a custom directory (here
`/export/home/someuser`):
```
mkdir -p /export/home
export NEWUID=20000
export NEWGID=20000
export USER_HOME=/export/home/someuser
/usr/sbin/groupadd -g $NEWGID someuser
/usr/sbin/useradd -u $NEWUID -d $USER_HOME -m -g $NEWGID someuser
```
Then connecting using this new user, and running initdb, then scheduler:
```
su someuser
airflow initdb
airflow scheduler
```
`initdb` runs fine and creates files in `/export/home/someuser/airflow`
When running `airflow scheduler`, the following error happens:
```

**BUT:** When you do the exact same steps, but with a home in
`/home/someuser` instead of `/export/home/someuser` it works fine, which really
makes no sense at all:
```
export NEWUID=20000
export NEWGID=20000
export USER_HOME=/home/someuser
/usr/sbin/groupadd -g $NEWGID someuser
/usr/sbin/useradd -u $NEWUID -d $USER_HOME -m -g $NEWGID someuser
```
Then connecting using this new user, and running initdb, then scheduler:
```
su someuser
airflow initdb
airflow scheduler
```
`initdb` runs fine and creates files in `/export/home/someuser/airflow`
When running `airflow scheduler`, the following error happens:

**What you expected to happen**:
Something is probably wrong in
[here](https://github.com/apache/airflow/blob/v1-10-stable/airflow/utils/log/file_processor_handler.py#L135)
when constructing relative paths, _render_filename takes as input
`filename=/usr/local/lib/python3.8/dist-packages/airflow/example_dags/example_docker_swarm_operator.py`
and
[here](https://github.com/apache/airflow/blob/v1-10-stable/airflow/utils/log/file_processor_handler.py#L87)
`filename = os.path.relpath(filename, self.dag_dir)` takes
`self.dag_dir=/home/airflow/airflow_data/dags` as the second argument, which
results in
`filename=../../../../../usr/local/lib/python3.8/dist-packages/airflow/example_dags/example_docker_swarm_operator.py`
which is probably not a correct path.
And i really don't get why it works with a user in /home, and not an user in
/export/home.
**How to reproduce it**:
To reproduce, build the following docker image:
```
ARG BASE_IMAGE="ubuntu:20.04"
FROM ${BASE_IMAGE} as min
SHELL ["/bin/bash", "-o", "pipefail", "-e", "-u", "-x", "-c"]
ARG AIRFLOW_VERSION="1.10.12"
ENV AIRFLOW_VERSION=$AIRFLOW_VERSION
# Make sure noninteractive debian install is used and language variables set
ENV DEBIAN_FRONTEND=noninteractive LANGUAGE=C.UTF-8 LANG=C.UTF-8
LC_ALL=C.UTF-8 \
LC_CTYPE=C.UTF-8 LC_MESSAGES=C.UTF-8
# Install basic and additional apt dependencies
RUN apt-get update \
&& apt-get install -y --no-install-recommends \
python3 \

# Setup PIP

ARG PIP_NO_CACHE_DIR="true"
ENV PIP_NO_CACHE_DIR=${PIP_NO_CACHE_DIR}
RUN echo "Pip no cache dir: ${PIP_NO_CACHE_DIR}"
RUN http_proxy=$http_proxy https_proxy=$http_proxy pip3 install
apache-airflow==$AIRFLOW_VERSION
ENTRYPOINT ["/bin/bash"]
```
```
docker build -t airflow_1.10.12 .
```
Then run the image:
```
docker run --name=airflow_test -it airflow_1.10.12
```
And execute the above commands.
Thanks for your help.
