bash - How determine Hive database size? -


how determine hive's database size bash or hive cli?

hdfs , hadoop commands avaliable in bash.

a database in hive metadata storage - meaning holds information tables , has default location. tables in database can stored anywhere in hdfs if location specified when creating table.

you can see tables in database using show tables command in hive cli.

then, each table, can find location in hdfs using describe formatted <table name> (again in hive cli).

last, each table can find size using hdfs dfs -du -s -h /table/location/

i don't think there's single command measure sum of sizes of tables of database. however, should easy write script automates above steps. hive can invoked bash cli using: hive -e '<hive command>'

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
