> Currently {{*add_partitions_xxx*}} will log the complete information of a partition if it already exists, see in [HMSHandler.java#L4320|https://github.com/apache/hive/blob/e3751ab545370f9b252d0b4a07bc315037541a95/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/HMSHandler.java#L4320]:
> {code:java}
>     if (!shouldAdd) {
>       LOG.info("Not adding partition {} as it already exists", part);
>       return false;
>     }
> {code}
> It will print a long message including the columns of this partition, we think it is unnecessary based on the following two points:
> {color:red}1. The long message is redundant.{color}
> We can get enough information from just *cat_name.db_name.tbl_name[part_col1=part_val1/part_col2=part_val2...]*
> {color:red}2. The long message is not friendly to save and query.{color}
> This log message will take up a large log space especially when the user need to execute *MSCK REPAIR TABLE* operation regularly because the old partition must be already existed.
