ATTACHMENT ID: 12747929 - PreCommit-HIVE-TRUNK-Build > Hive CLI startup takes a long time with a large number of databases > ------------------------------------------------------------------- > > Key: HIVE-10319 > URL: https://issues.apache.org/jira/browse/HIVE-10319 > Project: Hive > Issue Type: Improvement > Components: CLI > Affects Versions: 1.0.0 > Reporter: Nezih Yigitbasi > Assignee: Nezih Yigitbasi > Attachments: HIVE-10319.1.patch, HIVE-10319.2.patch, > HIVE-10319.3.patch, HIVE-10319.4.patch, HIVE-10319.5.patch, HIVE-10319.patch > > > The Hive CLI takes a long time to start when there is a large number of > databases in the DW. I think the root cause is the way permanent UDFs are > loaded from the metastore. When I looked at the logs and the source code I > see that at startup Hive first gets all the databases from the metastore and > then for each database it makes a metastore call to get the permanent > functions for that database [see Hive.java | > https://github.com/apache/hive/blob/trunk/ql/src/java/org/apache/hadoop/hive/ql/metadata/Hive.java#L162-185]. > So the number of metastore calls made is in the order of the number of > databases. In production we have several hundreds of databases so Hive makes > several hundreds of RPC calls during startup, taking 30+ seconds. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
