    Hello Avi,

    I would suggest you to go through Hadoop Admin, daily blog posts, FAQ and Ask Questions section and it may help you to prepare for interview.

Hi Saurabh, I am facing an issue with some of our hive queries. The queries are fine themselves. We see that sometimes the hive query returns a vertex failure and fails. the vertex keeps retrying for some times and then returns DAG failed. This happens randomly and not specific to one hive query. I guess it may be due to multiple jobs which are run at similar timing causing some kind of concurrency issue but not sure. Can you reply your idea on what could be the reason of such issue and how can we avoid it.
