IMPALA-2521 introduced clustering for insert statements. This change makes the HdfsTableSink aware of clustered inputs, so that partitions are opened, written, and closed one by one. This change also adds/modifies tests in several ways: - clustered insert tests switch from selecting all rows from alltypessmall to alltypes. Together with varying settings for batch_size, this results in a larger number of row batches being written. - clustered insert tests select from alltypes instead of functional.alltypes to make sure we also select from various input formats. - clustered insert tests have been added to select from alltypestiny to create inserts with 1 and 2 rows per partition respectively. - exhaustive insert tests now use different values for batch_size: 1, 16, 0 (meaning default, 1024). This is limited to uncompressed parquet files, to maintain a reasonable runtime. On my machine execution of test.insert took 1778 seconds, compared to 1002 seconds with the just default row batch size. - There is additional testing in test_insert_behaviour.py to make sure that insertion over several row batches only creates one file per partition. - It renames the test_insert method to make it unique in the file and allow for effective filtering with -k. - It adds tests to the Analyzer test suite.
