Change subject: IMPALA-13122: Add detailed file metadata statistics to table 
loading logs
......................................................................


Patch Set 2:

About the catalogd logs: assert_catalogd_log_contains() is only used in custom 
cluster tests, probably it doesn't work in normal tests.
The following suggests that it may need non-default flags to work:
https://github.com/apache/impala/blob/3dac0135fba0717dd977043e7ecc6b52bf55189f/tests/common/impala_test_suite.py#L1664C7-L1664C18

It also doesn't seem reliable in EE tests by design, even if only one test is 
run in parallel: the function doesn't check if the log line comes from the 
given query (e.g. by checking timestamp of log lines) and a previous test can 
make the log "dirty". This is ok in tests that always restart catalog (and 
create a new log file).

It would be nice to improve the log detection logic by ignoring older log 
lines, but in this case I think that it is ok to simply not write automatic 
tests at all and just write in the commit message that the logs were checked 
manually.
