> Key: TAJO-1289

> Project: Tajo
> Issue Type: Bug
> Components: tajo master

> Fix For: 0.10

> When a query execution is successfully finished, its status is written into a query history. Once the history is written, the tajo master gets the status of the finished query from that written history.
> Here, when the tajo master reads the query history, an I/O exception occurs and the tajo cli stops forever. Here is the full stack trace.
