Hi All, This discussion is related to DRILL-2322. It looks like Drill processes non-printable characters in both cases, with and without the new text reader (exec.storage.enable_new_text_reader)
Should we throw an error since these are non-printable characters ? for more details please take a look at JIRA DRILL-2322 Content from the csv file used in test 1,^A 2,^B 3,^C 4,^D 5,^E 6,^F 0: jdbc:drill:schema=dfs.tmp> select * from `nonPrintables.csv`; +-----------------+ | columns | +-----------------+ | ["1","\u0001"] | | ["2","\u0002"] | | ["3","\u0003"] | | ["4","\u0004"] | | ["5","\u0005"] | | ["6","\u0006"] | +-----------------+ 6 rows selected (0.521 seconds) 0: jdbc:drill:schema=dfs.tmp> select columns[1] from `nonPrintables.csv`; +---------+ | EXPR$0 | +---------+ | | | | | | | | | | | | +---------+ 6 rows selected (0.382 seconds) Thanks, Khurram
