--------------------------------------
Summary: Add a way to get the current file from a minidump for an
IO / scanner thread
Key: IMPALA-12124
URL: https://issues.apache.org/jira/browse/IMPALA-12124
Project: IMPALA
Issue Type: Improvement
Components: Backend
Affects Versions: Impala 4.3.0
Reporter: Joe McDonnell
In the past, there have been bugs in how Impala handles corrupt data files.
This can be difficult to diagnose without knowing the name of the corrupt data
file, but this is not easy to find if Impala crashes.
Impala has some thread information that it keeps on the stack to help identify
threads and the current query if Impala crashes. These are printed to the
Impala log by the minidump logic, and it can be retrieved using gdb after
converting the minidump to a core.
It would be useful to have something similar for the file / scan range that the
DiskIOMgr thread or scanner thread is working on. This would speed diagnosis
for these corruption cases (and can identify the table that is being scanned).
