**Apache Airflow version**: 1.10.10
**Kubernetes version (if you are using kubernetes)** (use `kubectl version`):
**Environment**:
- **Cloud provider or hardware configuration**: Google Cloud
- **OS** (e.g. from /etc/os-release): Ubuntu 18.04.4 LTS
- **Kernel** (e.g. `uname -a`): Linux int-vidio-stats-airflow-bionic
5.0.0-1034-gcp #35-Ubuntu SMP Tue Mar 17 03:56:45 UTC 2020 x86_64 x86_64 x86_64
GNU/Linux
- **Install tools**: pip
- **Others**:
**What happened**:
Recently, we upgraded airflow version from v1.10.5 to v1.10.10 due to
airflow instance that upgraded to ubuntu bionic. Existing dag configuration
having tags as list causes an issue at some jobs that use Qubole.
Error log:
```
Traceback (most recent call last):

AttributeError: 'set' object has no attribute 'extend'
```
**What you expected to happen**:
the tags should be included as a comma separated arguments to the build
command.
**How to reproduce it**:
using sample dag having list tags
```
t2 = QuboleOperator(
task_id='hive_gcs_location',
command_type="hivecmd",
script_location="s3n://public-qubole/qbol-library/scripts/show_table.hql",
notify=True,
tags=['tag1', 'tag2'],
trigger_rule="all_done"
)
```
and do an airflow run.
