[jira] [Commented] (IMPALA-5845) Impala should de-duplicate row parsing error
[ https://issues.apache.org/jira/browse/IMPALA-5845?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17552017#comment-17552017 ]

Commit 7273cfdfb901b9ef564c2737cf00c7a8abb57f07 in impala's branch refs/heads/master from Riza Suminto
[ https://gitbox.apache.org/repos/asf?p=impala.git;h=7273cfdfb ]
IMPALA-5845: Limit the number of non-fatal errors logging to INFO
RuntimeState::LogError() does both error aggregation to the coordinator
and logging the error to the log file depending on the vlog_level. This
can flood INFO log if the specified vlog_level is 1 and makes it
difficult to analyze other more significant log lines. This patch limits
the number of errors logged to INFO based on max_error_logs_per_instance
flag (default is 2000). When this number is exceeded, vlog_level=1 will
be downgraded to vlog_level=2.
To allow easy debugging in the future, this flag will be ignored if the
user sets query option max_errors < 0, which in that case all errors
targetting vlog_level 1 will be logged.
This patch also fixes a bug where the error count is not increased for
non-general error code that is already in 'error_log_' map.
Testing:
- Add test_logging.py::TestLoggingCore

> I0824 10:44:46.527885 8679 runtime-state.cc:217] Error from query 804d64b80df65fda:a5349b0700000000: Error parsing row: file: hdfs://nameservice1/user/hive/tpcds.db/store_sales/00005.parq, before offset: 120795952
> There are 622000 errors for only 141 unique files
> Impala already de-duplicate similar error in lots of scenarios, could the row parsing error be de-duplicated as well to reduce log size and easier troubleshooting?
