Navis commented on HIVE-7575: ----------------------------- [~ychena] Sorry for my bad description. Retrieving all the Table instances from metastore is the the root cause of this, Not databases. For my case, I have 3000+ tables in 100+ databases. [~szehon] I thought at first "table_types" was also a patten like other params but actually it was not. Would it be better to be String[] or List<String>? [~aihuaxu] There are already some test cases (TestJdbcDriver2, for example) but I think I can add some more. Thanks. > GetTables thrift call is very slow > ---------------------------------- > > Key: HIVE-7575 > URL: https://issues.apache.org/jira/browse/HIVE-7575 > Project: Hive > Issue Type: Bug > Components: HiveServer2 > Affects Versions: 0.12.0, 0.13.0 > Reporter: Ashu Pachauri > Assignee: Navis > Attachments: HIVE-7575.1.patch.txt, HIVE-7575.2.patch.txt, > HIVE-7575.3.patch.txt > > > The GetTables thrift call takes a long time when the number of table is large. > With around 5000 tables, the call takes around 80 seconds compared to a "Show > Tables" query on the same HiveServer2 instance which takes 3-7 seconds. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
