8. Why Hive?
Handmade MapReduce: Noooooooooooooooo
Pig? Hive?
All we loves 'xQL' like 'SQL'...
FORCE to throw away all queries
"処理を書き捨てる勇気"
We are likely to maintain 'programs' (like pig script)
With chainging data, BAD to maintain how to handle
data

9. Client Tools?
'hive' command sucks
Hue (Beeswax for Hive)？
we want end-users to run 'SELECT' only.
we want HTTP API to work with another systems
Periodic query execution, and graph plotting
Miscellaneous extensions we want (and ease to write)

Hive Client Web Application
Run 'SELECT' queries only
Store results of queries
Provides HTTP API:
to run queries
to get result data of queries
