Please address them and squash the commits into one. Also I have run Functional and Advanced tests for your branch and there is one test failure: ``` Query: /root/drillAutomation/drill-test-framework/framework/resources/Functional/filter/pushdown/data/DRILL_6259_filter_push_down_top_level_array.sql select * from dfs.drillTestDir.`parquet_storage/DRILL_6259/DRILL_6259_test_data` t where t.top_level_array[2] >= 20 Baseline: /root/drillAutomation/drill-test-framework/framework/resources/Functional/filter/pushdown/data/DRILL_6259_filter_push_down_top_level_array.e_tsv Expected number of rows: 1 Actual number of rows from Drill: 2 Number of matching rows: 1 Number of rows missing: 0 Number of rows unexpected: 1 These rows are not expected (first 10): d3 3 1487165823000 [31,32] {"nested_array":[false,true,false,false],"nested_complex_field":{"nested_array":[true,false,false,true]},"nested_list_of_complex_fields":[{"nested_array":[1131,1132,1133,1134]},{"nested_field":1485400063000,"nested_array":[1134,1135,1136,1137]},{"nested_field":1485488351000,"nested_array":[1137,1138,1139,1140]}]} [{"nested_array":[131,132,133,134],"nested_complex_field":{"nested_array":[1485576639000,1485663099000]},"nested_list_of_complex_fields":[{"nested_array":[1131,1133]},{"nested_field":true,"nested_array":[1134,1135,1136,1137]},{"nested_field":false,"nested_array":[1137,1138,1139]}]},{"nested_field":true,"nested_array":[321,322,323],"nested_complex_field":{"nested_field":321,"nested_array":[1488255039000,1488255099000,1488341499000]},"nested_list_of_complex_fields":[{"nested_field":false,"nested_array":[1321,1322,1323]},{"nested_field":true,"nested_array":[1324,1325,1326]},{"nested_field":false,"nested_array":[1327,1328,1329]}]},{"nested_field":true,"nested_array":[331,332,333],"nested_complex_field":{"nested_field":331,"nested_array":[1489774239000,1489774299000,1489860699000]},"nested_list_of_complex_fields":[{"nested_field":false,"nested_array":[1331,1332,1333]},{"nested_field":true,"nested_array":[1334,1335,1336]},{"nested_field":true,"nested_array":[1337,1338,1339]}]}] ``` Data - https://github.com/mapr/drill-test-framework/tree/master/framework/resources/Datasources/parquet_storage/DRILL_6259/DRILL_6259_test_data Query - https://github.com/mapr/drill-test-framework/blob/master/framework/resources/Functional/filter/pushdown/data/DRILL_6259_filter_push_down_top_level_array.sql Expected result - https://github.com/mapr/drill-test-framework/blob/master/framework/resources/Functional/filter/pushdown/data/DRILL_6259_filter_push_down_top_level_array.e_tsv Please fix it. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.

This means > you can remove a partition only if the whole file is for the same partition. > With parquet, you can prune the filter if the rowgroup make a partition of > your dataset as the unit of work if the rowgroup not the file. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
