> metastore setconf API can set too many confs

> {noformat}
> public void setMetaConf(String key, String value) throws MetaException {
> ConfVars confVar = HiveConf.getMetaConf(key);
> {noformat}
> that gets stuff from "metaConfs", which contains all the metastore configs,
> including the warehouse location, port (setting that unfortunately would not
> work; imagine the possibilities!), etc.
> There's another small list near metaConfs - metaConfVars, billed as "User
> configurable Metastore vars". That is probably the list that should be used;
> as it is, it's not used for any checks.
> When making the change SetProcessor etc. should be adjusted to fail with some
> user-friendly message when trying to set unsettable metastore APIs.
