Hm, the CI errors seems unrelated to the PR:

 pip install .[avro] coverage mock
before_script.1
0.35s$ export HADOOP_HOME="$(./scripts/hadoop.sh download)"
before_script.2
0.02s$ export HADOOP_CONF_DIR="$(./scripts/hadoop.sh config)"
0.01s$ ./scripts/hadoop.sh start
./scripts/hadoop.sh: line 67: /bin/hdfs: No such file or directory

The command "./scripts/hadoop.sh start" failed and exited with 1 during .
