[jira] [Commented] (AIRFLOW-1797) Cannot write task logs to S3 with Python3

ASF subversion and git services commented on AIRFLOW-1797:
----------------------------------------------------------

Commit 28411b1e7eddb3338a329db3e52ee09de3676784 in incubator-airflow's branch refs/heads/master from [~ashb]
[ https://git-wip-us.apache.org/repos/asf?p=incubator-airflow.git;h=28411b1 ]

[AIRFLOW-1797] S3Hook.load_string didn't work on Python3

With the switch to Boto3 we now need the content
to be bytes, not a
string. On Python2 there is no difference, but for
Python3 this matters.

And since there were no real tests covering the
S3Hook I've added some
basic ones.

Closes #2771 from ashb/AIRFLOW-1797
