# Setup data

run this from your teminal 

sudo su druid
wget https://transfer.sh/sWgBK/wikiticker-2015-09-12-sampled.json.gz
gunzip wikiticker-2015-09-12-sampled.json.gz
hdfs dfs -ls /apps/druid
hdfs dfs -put wikiticker-2015-09-12-sampled.json /apps/druid/warehouse

# Index data via curl

wget https://transfer.sh/5W3Nh/index_task_hdfs.json

Explain the task spec:

- type of task
- data source name
- path to the data
- specs of partition


curl -X 'POST' -H 'Content-Type:application/json' -d@index-task.json ctr-e134-1499953498516-247377-01-000004.hwx.site:8090/druid/indexer/v1/task

Look at the orveloard UI look at the indexing log

Look at the coordinator UI look at the load status

# Query the data 

## Time Boundary
wget https://transfer.sh/wzxR2/timeBoundary.json
curl -X POST "ctr-e134-1499953498516-247377-01-000002.hwx.site:8888/druid/v2/?pretty" -H 'content-type: application/json' -d@timeBoundary.json

https://transfer.sh/Ta26s/topN.json
curl -X POST "ctr-e134-1499953498516-247377-01-000002.hwx.site:8888/druid/v2/?pretty" -H 'content-type: application/json' -d@topN.json

## Practice 
write/run your own query using druid select query help page 

# SuperSet UI
Via Ambari UI Go to Superset and create some simple slice

# Hive QL

```sql
CREATE EXTERNAL TABLE wikipedia
STORED BY 'org.apache.hadoop.hive.druid.DruidStorageHandler'
TBLPROPERTIES ("druid.datasource" = "wikipedia");
```

##Query the existing data

```sql
DESCRIBE FORMATTED  wikipedia;
SELECT * FROM wikipedia LIMIT 10;
SELECT COUNT(*) FROM wikipedia;
SELECT COUNT(*), floor_hour(`__time`) FROM wikipedia GROUP BY floor_hour(`__time`);
```


## Index more data 


## Query the data 



# Delete the data source 


# Msc commands
to kill yarn app
yarn application -kill  application_1508802793765_0005
