----------------------------------------
Summary: Segfault when selecting >500 columns with a filter
Key: IMPALA-12348
URL: https://issues.apache.org/jira/browse/IMPALA-12348
Project: IMPALA
Issue Type: Bug
Components: be
Affects Versions: Impala 4.2.0
Reporter: Saulius Valatka
Attachments: 89da31ae-cc29-4394-e8c984a6-f9d9eeb3.dmp, gdb.txt
Impala daemon consistently crashes with a segfault when selecting a few hundred
columns with a filter from a Parquet based table, i.e.: a query like:
{{select x1, x2, ..., x500 from table where x1 = 'value' limit 100}}
It doesn't seem to matter what columns are selected/filtered, as long as a
certain threshold is reached. Interestingly it does not crash without the
filter. Same queries did not crash with Impala 3.2.0.
Attached a gdb backtrace from a debug build. Also attached a minidump, but I
see it's only showing ?? backtraces for some reason.
