> HIVE-23281 optimizes StorageDescriptor conversion as part of the ObjectStore
> by skipping particular Table properties like SkewInfo, bucketCols, ordering
> etc.
> However, it does that for all Transactional Tables – not only ACID – causing
> MicroManaged Tables to behave abnormally.
> MicroManaged (insert_only) tables may miss needed properties such as Storage
> Desc Params – that may define how lines are delimited (like in the example
> below):
> To repro the issue:
> {code:java}
> CREATE TRANSACTIONAL TABLE delim_table_trans(id INT, name STRING, safety INT)
> ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t' STORED AS TEXTFILE;
> LOAD DATA INPATH 'table1' OVERWRITE INTO TABLE delim_table_trans;
> describe formatted delim_table_trans;
> SELECT * FROM delim_table_trans;
> {code}
> Result:
> {code:java}
> Table Type: MANAGED_TABLE
> Table Parameters:
> bucketing_version 2
> numFiles 1
> numRows 0
> rawDataSize 0
> totalSize 72
> transactional true
> transactional_properties insert_only
