--------------------------------------

             Summary: Test test_recover_many_partitions is very slow on S3, 
Ozone
                 Key: IMPALA-12080
                 URL: https://issues.apache.org/jira/browse/IMPALA-12080
             Project: IMPALA
          Issue Type: Task
          Components: Infrastructure
            Reporter: Michael Smith


The test 
metadata/test_recover_partitions.py::TestRecoverPartitions::test_recover_many_partitions
 takes <2 minutes for HDFS runs, ~1 hour for Ozone and S3 tests. This appears 
to be because test setup invokes a filesystem client 1400 times, to create 
directories and files for 700 partitions. With HDFS that's fast because it uses 
[pywebhdfs|https://pypi.org/project/pywebhdfs/] to do it in-process, but for 
all other filesystems it defaults to the hdfs Java CLI.
