I am new with azkaban, i am also trying to start azkaban web server but i am facing error "temp directory must be set!"  how can i set that, i am new with azkaban.
for starting azkaban web server, i am using below command
./bin/azkaban-web-start.sh

即需要使用bin/azkaban-web-start.sh 进行启动，不能azkaban-web-start.sh ，估计是个Bug
