Alan Woodward 91e2330529 Warn on badly-formed null values for date and IP field mappers (#62487) ... In #57666 we changed when null_value was parsed for ip and date fields. Previously, the null value was stored as a string, and parsed into a date or InetAddress whenever a document containing a null value was encountered. Now, the values are parsed when the mappings are built, which means that bad values are detected up front; if you try and add a mapping with a badly-parsed ip or date for a null_value, the mapping will be rejected. This causes problems for upgrades in the case when you have a badly-formed null_value in a pre-7.9 cluster. This commit fixes the upgrade case by changing the logic to only logging a warning on the badly formed value, replicating the earlier behaviour. Fixes #62363		2020-09-17 16:38:08 +01:00
