rc33 when drop the database, we found the database has not actually been dropped.

[ziyel]

scenario 1:

I have run below lines in the influx cli.

> drop database justtest
> create database justtest
> use justtest
Using database justtest
> show measurements
name: measurements
------------------
name
test.test.test.test2

I can show the measurements after recreating the database justtest.

scenario 2:

1 Insert a point with line protocol.

test.test.test.test2,host=host value="20",value2="20" 1434009080000000000

2 Select the results in influx cil.

> select * from "test.test.test.test2"
name: test.test.test.test2
tags: host=host
time            value   value2
----            -----   ------
2015-06-11T07:51:20Z    20  20

3 Drop and create the database with the same name.

> drop database justtest
> create database justtest

4 Insert a point without value2 field.

test.test.test.test2,host=host value="20" 1434009080000000000

5 Select again.

> select * from "test.test.test.test2"
name: test.test.test.test2
tags: host=host
time            value   value2
----            -----   ------
2015-06-11T07:51:20Z    20

We can still see the value2 field.

Any ideas about this?
Thanks in advance.

Looks like the points are gone but the database metadata persists:

> drop database mydb
> create database mydb
> use mydb
Using database mydb
> show measurements
name: measurements
------------------
name
triangle
triangle-float

> select * from triangle
> select value from triangle
> show series
name: triangle
--------------
_key            tagkey
triangle,tagkey=tagval  tagval


name: triangle-float
--------------------
_key                tagkey2
triangle-float,tagkey2=tagval1  tagval1

Bouncing the database between the drop and create database statements appears to alleviate the issue, pointing I think convincingly at the metadata store being the culprit.

> drop database mydb
> show databases
ERR: Get http://localhost:8086/query?db=&q=show+databases: dial tcp 127.0.0.1:8086: connection refused
> show databases

> use mydb
Using database mydb

> select value from triangle
