Subject [Hadoop Wiki] Trivial Update of "Hive/LanguageManual/DML" by JoydeepSensarma
Date Thu, 22 Jan 2009 01:31:12 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.

The following page has been changed by JoydeepSensarma:

   * if LOCAL keyword is used - then Hive will write data to the directory on the local file
   * Data written to the filesystem is serialized as text with columns separated by ^A and
rows separated by newlines. If any of the columns are not of primitive type - then those columns
are serialized to JSON format.
- ===== Notes ====
+ ===== Notes =====
   * Insert statements to directories, local directories and tables (or partitions) can all
be used together within the same query.
   * Inserts to HDFS filesystem directories is the best way to extract large amounts of data
from Hive. Hive can write to HDFS directories in parallel from within a map-reduce job.
