--------------------------------------
Summary: impala-shell with Python 3 mangles binary output
Key: IMPALA-12517
URL: https://issues.apache.org/jira/browse/IMPALA-12517
Project: IMPALA
Issue Type: Bug
Affects Versions: Impala 4.3.0
Reporter: Michael Smith
With a table containing binary data such as
{code}
CREATE TABLE complex_datatype (A INT, b BINARY);
INSERT INTO complex_datatype VALUES (1, CAST("a" as BINARY)), (2, CAST("8" as
BINARY)), (3, CAST(NULL as BINARY));
{code}
querying it with Python 3 mangles the output by prefixing it with 'b' and
quoting it
{code}
$ IMPALA_PYTHON_EXECUTABLE=python3 impala-shell.sh -q 'select * from
complex_datatype'
...
+---+------+
| a | b |
+---+------+
| 1 | b'a' |
| 2 | b'8' |
| 3 | NULL |
+---+------+
Fetched 3 row(s) in 0.11s
{code}
This should look like
{code}
+---+------+
| a | b |
+---+------+
| 1 | a |
| 2 | 8 |
| 3 | NULL |
+---+------+
{code}
Behaves the same when outputting to a file as well, with and without {{-B}}.
