I have a hive external table partitioned on dt(string).
Some values in partitioned column are none, which means that these rows go into the null partition(dt=HIVE_DEFAULT_PARTITION). I want to update location for this partition.
0: jdbc:hive2://localhost:10000/> alter table `zdb.table` partition(dt=__HIVE_DEFAULT_PARTITION__) set location "s3a://path/zdb.db/table/dt=__HIVE_DEFAULT_PARTITION__";

Also, I noticed that drop partition is working
0: jdbc:hive2://localhost:10000/> alter table `zdb.table` drop partition(dt="__HIVE_DEFAULT_PARTITION__") ;
No rows affected (0.08 seconds)
Using the same syntax with add partition fails
0: jdbc:hive2://localhost:10000/> alter table `zdb.table` add partition(dt="__HIVE_DEFAULT_PARTITION__") location "s3a://path/zdb.db/table/dt=__HIVE_DEFAULT_PARTITION__";
Error: Error while compiling statement: FAILED: SemanticException [Error 10111]: Partition value contains a reserved substring (User value: __HIVE_DEFAULT_PARTITION__ Reserved substring: __HIVE_DEFAULT_PARTITION__) (state=42000,code=10111)
For my use-case, I cannot use msck repair table <table-name>. Please suggest if there is a work-around for this
