Ensure the table is set to external, drop all partitions then run the table repair:

alter table mytable_name set TBLPROPERTIES('EXTERNAL'='TRUE')
alter table mytable_name drop if exists partition (`mypart_name` <> 'null');
msck repair table mytable_name;

If msck repair throws an error, then run hive from the terminal as:
hive --hiveconf hive.msck.path.validation=ignore
or set hive.msck.path.validation=ignore;
