jinxing64 opened a new pull request, #5534:
URL: https://github.com/apache/hudi/pull/5534
## What is the purpose of the pull request
In current code, AlterHoodieTableDropPartitionCommand and
TruncateHoodieTableCommand require all partition fields should be specified
when droping / truncating partitions(s), otherwise complain with
AnalyisException (HoodieSqlCommonUtils#normalizePartitionSpec).
But native Spark/Hive SQL have no such limitations – – partition matching is
provided as a functionality helping user to manage partition(s) in an easy way.
Say dropping partitions with a single SQL "alter table test drop partition
(year='2020')", but rather to specify all the partitions from (year='2020',
month='01', day='01') to (year='2020', month='12', day='31')
This PR propose to refine the partition matching logic when drop / truncate
partition and remove the limitation mentioned above.
