             Summary: TestInsertParquetQueries.test_insert_parquet is flaky in S3 due to rename
                 Key: IMPALA-7733
                 URL: https://issues.apache.org/jira/browse/IMPALA-7733
             Project: IMPALA
          Issue Type: Bug
          Components: Infrastructure
    Affects Versions: Impala 3.1.0
            Reporter: Vuk Ercegovac


I see two examples in the past two months or so where this test fails due to a rename error on S3. The test's stacktrace looks like this:
{noformat}
query_test/test_insert_parquet.py:112: in test_insert_parquet
    self.run_test_case('insert_parquet', vector, unique_database, multiple_impalad=True)
common/impala_test_suite.py:408: in run_test_case
    result = self.__execute_query(target_impalad_client, query, user=user)
common/impala_test_suite.py:625: in __execute_query
    return impalad_client.execute(query, user=user)
common/impala_connection.py:160: in execute
    return self.__beeswax_client.execute(sql_stmt, user=user)
beeswax/impala_beeswax.py:176: in execute
    handle = self.__execute_query(query_string.strip(), user=user)
beeswax/impala_beeswax.py:350: in __execute_query
    self.wait_for_finished(handle)
beeswax/impala_beeswax.py:371: in wait_for_finished
    raise ImpalaBeeswaxException("Query aborted:" + error_log, None)
E   ImpalaBeeswaxException: ImpalaBeeswaxException:

First error (of 1) was: Hdfs op (RENAME s3a://<removed>/test_insert_parquet_968f37fe.db/orders_insert_table/_impala_insert_staging/4e45cd68bcddd451_3c7156ed00000000/.4e45cd68bcddd451-3c7156ed00000002_803672621_dir/4e45cd68bcddd451-3c7156ed00000002_448261088_data.0.parq TO s3a://<removed>/test-warehouse/test_insert_parquet_968f37fe.db/orders_insert_table/4e45cd68bcddd451-3c7156ed00000002_448261088_data.0.parq) failed, error was: s3a://<removed>/test-warehouse/test_insert_parquet_968f37fe.db/orders_insert_table/_impala_insert_staging/4e45cd68bcddd451_3c7156ed00000000/.4e45cd68bcddd451-3c7156ed00000002_803672621_dir/4e45cd68bcddd451-3c7156ed00000002_448261088_data.0.parq
E   Error(5): Input/output error{noformat}
Since we know this happens once in a while, some ideas to deflake it:
 * retry
 * check for this specific issue... if we think its platform flakiness, then we should skip it.
