[ADLSGen2][TCK] Unable to read the delta lake table if a partition is used

[ADLSGen2][TCK] Unable to read the delta lake table if a partition is used. 

Suppose a Deltalake Table is created with a partition, 

spark.sql("CREATE TABLE cars_partition_new (id STRING, name STRING, release STRING, sales STRING, outofdate STRING) USING DELTA PARTITIONED BY (outofdate) LOCATION '/mnt/test/From_Deltalake_Partition'")

 Then insert the source data into the DetlaLake table, and check the inserted content with Delta Reader in the ADLSGen2. The result is illustrated by, where the partition column (outofdate) is empty.
