ZhaoYang commented on CASSANDRA-13573:
--------------------------------------

Some issues are related to {{ColumnMetadata.cellValueType()}} which currently : 
 {{a}}. if CollectionType, returns value's type; {{b}} otherwise,  its own type.

It doesn't handle properly:  {{1}}. frozen collection type,  {{2}}. non-frozen 
udt which requires cellPath to retrieve value's type..  




> sstabledump doesn't print out tombstone information for frozen set collection
