The partition's > metadata in mysql has been deleted, but the exception is still thrown. it > will failed if using jdbc by java to connec hiveserver2, I think it is very > unfriendly and we should fix it. > Example: > -- First, create manage table with nulti partition columns, and add > partitions: > {code:java} > drop table if exists t1; > create table t1 (c1 int) partitioned by (year string, month string, day > string); > alter table t1 add partition(year='2019', month='07', day='01');{code} > -- Second, delete the path of partition 'month=07': > > {code:java} > hadoop fs -rm -r > /user/hadoop/xiepengjietest.db/drop_partition/year=2019/month=07{code} > > -- Third, when i try to drop partition, the metastore throws exception with > 'Failed to delete parent: File does not exist' . > > {code:java} > alter table t1 drop partition partition(year='2019', month='07', day='01'); > {code} > exception like this: > > > {code:java} > Error: Error while processing statement: FAILED: Execution Error, return code > 1 from org.apache.hadoop.hive.ql.exec.DDLTask.
