Why my metastore log has too many cmd=get_database

[#1]

Hi,every one:

    I have a question.I found there are many "cmd=get_database" log in hadoop-cmf-hive-HIVEMETASTORE.out file.But I haven't done this much.Is it because there are so many other actions that trigger it?

@Meepoljd yes. these calls were made, to get, metadata information from backend db (mysql, postgres) for each request comes in to hms for query processing.
