Aihua Xu commented on HIVE-16647:
---------------------------------
[~pvary] Ideally we should configure LOG so it can output to file or console.
Right now seems it's there so if I print to LOG and Console, it may print twice
if LOG is configured to print to console.
It's a good idea. I will file a followup jira to investigate that.
> Improve the validation output to make the output to stderr and stdout more
> consistent

> Some output are printed to stderr or stdout inconsistently. Here are some of
> them. Update to make them more consistent.
> * Version table validation
> When the version table is missing, the err msg goes to stderr
> When the version table is not valid, the err msg goes to stdout with a
> message like "Failed in schema version validation: <err_msg>
> * Metastore/schema table validation
> ** When the version table contains the wrong version or there are no rows in
> the version table, err msg goes to stderr
> ** When there diffs between the schema and metastore tables, the err msg goes
> to stdout
