--------------------------------------
Summary: impala-gdb.py's find-query-ids/find-fragment-instances
return unusable query ids
Key: IMPALA-13111
URL: https://issues.apache.org/jira/browse/IMPALA-13111
Project: IMPALA
Issue Type: Bug
Components: Infrastructure
Affects Versions: Impala 4.5.0
Reporter: Joe McDonnell
The gdb helpers in lib/python/impala_py_lib/gdb/impala-gdb.py provide
information about the queries / fragments running in a core file. However, the
query/fragment ids that it returns have issues with the signedness of the
integers:
{noformat}
(gdb) find-fragment-instances

3442ed6354c7355d:78c83d2000000000{noformat}
The low values for find-query-ids don't have this problem, because it is ANDed
with 0xFFFFFFFFFFFF0000:
{noformat}
qid_low = format(int(qid_low, 16) & 0xFFFFFFFFFFFF0000,
'x'){noformat}
We can fix the other locations by ANDing with 0xFFFFFFFFFFFFFFFF.
