[jira] [Commented] (IMPALA-9264) Support catalogd without HMS
[ https://issues.apache.org/jira/browse/IMPALA-9264?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17020634#comment-17020634 ]
Vihang Karajgaonkar commented on IMPALA-9264:
---------------------------------------------
Can please clarify what do you mean by "catalogd connected to mysql/pg directly"? Do you mean that the the HMS is instantiated in embedded mode in the coordinator? See [https://cwiki.apache.org/confluence/display/Hive/AdminManual+Metastore+Administration#AdminManualMetastoreAdministration-Local/EmbeddedMetastoreServer] if you need more details on different modes of HMS.

> In my company, catalogd connected to mysql/pg directly (instead of by metastore service) is a very common usage. And we just need to config hive-site.xml like this(metastore related config such as hive.metastore.uris is unnecessary):
> {code:java}
> <property>
> <name>javax.jdo.option.ConnectionDriverName</name>
> <value>org.postgresql.Driver</value>
> </property>
> <property>
> <name>javax.jdo.option.ConnectionPassword</name>
> <value>password</value>
> </property>
> <property>
> <name>javax.jdo.option.ConnectionURL</name>
> <value>jdbc:postgresql://localhost:5432/HMS_home_impala</value>
> </property>
> <property>
> <name>javax.jdo.option.ConnectionUserName</name>
> <value>hiveuser</value>
> </property>
> {code}
> Recently, when I test impala-3.3 in this situation, I found that created kudu managed table failed ([IMPALA-8974|https://issues.apache.org/jira/browse/IMPALA-8974]), and I've already fixed this.
> I guess there maybe other funcionality that have not been took into considertion in this situation. So I built this jira to collect those functionality, and I'm willing to continue contributing when I'm free.
