Subject clarification please
Date Thu, 29 Oct 2015 05:43:04 GMT
hi gurus,
kindly clarify the following please
   
   - Hive currently does not support indexes or indexes are not used in the query
   - The lowest granularity for concurrency is partition. If table is partitioned, then partition
will be lucked in DML operation
   - What is the best file format to store Hive table in HDFS? Is this ORC or Avro that allow
being split and support block compression?
   - Text/CSV files. By default if file type is not specified at creation time, Hive will
default to text file?


Thanks
