kylin-cube: 使用api来build, 定时执行job

获取用户名密码： 被base64加密后的格式：

UserName=ADMIN
Password=KYLIN
baseUsernamePasswd=`python -c "import base64; print base64.standard_b64encode('$UserName:$Password')"`

1，执行cube的相关任务

a, build/rebuild cube

curl -X PUT \
-H "Authorization: Basic $baseUsernamePasswd" \
-H "Content-Type: application/json" \
-d '{
    "startTime": 0,
    "endTime": 1388563200000,
    "buildType": "BUILD"
}' \
http://localhost:7070/kylin/api/cubes/ys_demo/build
#http://localhost:7070/kylin/api/cubes/ys_demo/rebuild

##数据返回
{"uuid":"2eb3c342-daa2-4fab-abb8-c622beb46d9b", ...}

b, 获取job的状态

curl -X GET \
-H "Authorization: Basic QURNSU46S1lMSU4=" \
-H "Content-Type: application/json" \
http://localhost:7070/kylin/api/jobs/cbfaf44f-c7bb-4b5a-9da4-671f6c84b1bb

##返回的数据
{...,"submitter":"ADMIN","job_status":"RUNNING","progress":53.84615384615385...}
