@paul-rogers is right, there is something wrong with the protos @dvjyothsna
has generated.
I took master branch and generated protos. No changes so these extra
changes we see are wrong. Also I have created branch where I have added changes
in protos from this PR [1] and from the diff it can be seen that no extra
changes as well [2].
@dvjyothsna please address this issue.
If it helps:
I have installed protoc:
```
protoc --version
libprotoc 2.5.0
```
and generated using the following:
```
cd ~/git_repo/drill/protocol
mvn process-sources -P proto-compile
```

>
> I think drill will benefit from mode of operation that is called "quiescent"
> in some databases.
> From IBM Informix server documentation:
> {code}
> Change gracefully from online to quiescent mode
> Take the database server gracefully from online mode to quiescent mode to
> restrict access to the database server without interrupting current
> processing. After you perform this task, the database server sets a flag that
> prevents new sessions from gaining access to the database server. The current
> sessions are allowed to finish processing. After you initiate the mode
> change, it cannot be canceled. During the mode change from online to
> quiescent, the database server is considered to be in Shutdown mode.
> {code}
> This is different from shutdown, when processes are terminated.
