> Lower Logging for "Table not found" Error
> -----------------------------------------
>
> Key: HIVE-18890
> URL: https://issues.apache.org/jira/browse/HIVE-18890
> Project: Hive
> Issue Type: Improvement
> Components: HiveServer2
> Affects Versions: 3.0.0
> Reporter: BELUGA BEHR
> Assignee: Manoj Narayanan
> Priority: Minor
> Attachments: HIVE-18890.1.patch

> https://github.com/apache/hive/blob/7cb31c03052b815665b3231f2e513b9e65d3ff8c/ql/src/java/org/apache/hadoop/hive/ql/metadata/Hive.java#L1105
> {code:java}
> // Get the table from metastore
> org.apache.hadoop.hive.metastore.api.Table tTable = null;
> try {
> tTable = getMSC().getTable(dbName, tableName);
> } catch (NoSuchObjectException e) {
> if (throwException) {
> LOG.error("Table " + tableName + " not found: " + e.getMessage());
> throw new InvalidTableException(tableName);
> }
> return null;
> } catch (Exception e) {
> throw new HiveException("Unable to fetch table " + tableName + ". " +
> e.getMessage(), e);
> }
> {code}
> We should throw an exception or log it, but not both. Right [~mdrob] ? ;)
> And in this case, we are generating scary ERROR level logging in the
> HiveServer2 logs needlessly. This should not be reported as an application
> error. It is a simple user error, indicated by catching the
> _NoSuchObjectException_ Throwable, that can always be ignored by the service.
> It is most likely a simple user typo of the table name. However, the more
> serious general _Exception_ is not logged. This is backwards.
> Please remove the _error_ level logging for the user error... or lower it to
> _debug_ level logging.
> Please include an _error_ level logging to the general Exception case, unless
> this Exception is being captured up the stack, somewhere else, and is being
> logged there at ERROR level logging.
