> When PhysicalOptimizer optimizes GroupByOperator, according to default parameters "hive.optimize.metadataonly = true", MetadataOnlyOptimizer will be enabled. The MetadataOnlyOptimizer will change the partition alias desc. The partition alies "hdfs://ip:9000/user/hive/warehouse/test/pts=12%3A11%3A30" is changed into "
> fake-path-metadata-only-query-default.test{pts=12:11:30}". When construct uri through new partition alies, it must occur java.net.URISyntaxException.
