> if (LOG.isDebugEnabled()) {
> LOG.warn("Failed to connect to the MetaStore Server...", e);
> } else {
> // Don't print full exception trace if DEBUG is not on.
> LOG.warn("Failed to connect to the MetaStore Server...");
> }
> {code}
> I do not understand the logic here. I always want to see the reason for the
> failure. Otherwise, I do not know why it is failing unless I restart the
> server with debug logging enabled. By that point, the error may have
> cleared. Please just use the Exception in the WARN output without adding
> confusing logging for debugging. This is never an expected behavior... that
> enabling debug would change a _warn_ level log message.
> Also... please remove the ellipsis, they add no value.
