metastore的ER图：https://issues.apache.org/jira/secure/attachment/12471108/HiveMetaStore.pdf

有两种配置方式，分别有本地和远程两种配置方法： metastore server和metastore database

非metastore相关的配置参数：参见一，参见二，metastore安全配置

基本的配置参数：

hive.metastore.warehouse.dir	URI of the default location for native tables
~~hive.metastore.local~~	local or remote metastore (removed as of Hive 0.10: If `hive.metastore.uris` is empty `local` mode is assumed, `remote` otherwise)
javax.jdo.option.ConnectionDriverName	JDBC Driver class name for the data store
javax.jdo.option.ConnectionURL	JDBC connection string for the data store
hive.metastore.uris（可配置多个，实现负载均衡，因为metastore无状态）	Hive connects to one of these URIs to make metadata requests to a remote Metastore (comma separated list of URIs)
