----------------------------------------
Summary: Remove false positive error log messages
Key: MINIFICPP-1694
URL: https://issues.apache.org/jira/browse/MINIFICPP-1694
Project: Apache NiFi MiNiFi C++
Issue Type: Bug
Reporter: Gábor Gyimesi
Assignee: Gábor Gyimesi
There are some error messages in MiNiFi that do not actually signal a real
error. There were instances when users observed these errors while debugging a
separate issue and they were suspicious that these might be related so these
messages can be quite misleading. Most common of these can be observed at
startup:
* Happens when "type" field is used instead of "class" which is also
acceptable:
{code:java}
[2021-11-29 13:43:52.892] [org::apache::nifi::minifi::core::YamlConfiguration]
[error] Unable to parse configuration file for component named
'AzureStorageCredentialsService' as required field 'class' is missing [in
'Controller Services' section of configuration file] [line:column, pos at 52:2,
1660] {code}
* This should probably be a warning if no configuration file is defined and
the default is not available:
{code:java}
[2021-11-29 13:43:52.898] [org::apache::nifi::minifi::Properties] [error] load
configure file failed{code}
* When component state not available anymore this can be also ignored, so it
should not be an error:
{code:java}
[2021-11-29 13:43:52.919]
[org::apache::nifi::minifi::controllers::RocksDbPersistableKeyValueStoreService]
[error] Failed to Get key 94b8e610-b4ed-1ec9-b26f-c839931bf3e2 from RocksDB
database at corecomponentstate, error: (null){code}
