Hi, all:
    I am trying to use carbon,  but I am confused about the properties as blow:


carbon.storelocation=hdfs://hacluster/Opt/CarbonStore
#Base directory for Data files
carbon.ddl.base.hdfs.url=hdfs://hacluster/opt/data
#Path where the bad records are stored
carbon.badRecords.location=/opt/Carbon/Spark/badrecords





Why do I need to set carbon.storelocation and  carbon.ddl.base.hdfs.url before 
I create carbon table?


Best Regards
yuhai
