Lefty Leverenz updated HIVE-1841: --------------------------------- Labels: TODOC2.0 (was: ) > datanucleus.fixedDatastore should be true in hive-default.xml > -------------------------------------------------------------- > > Key: HIVE-1841 > URL: https://issues.apache.org/jira/browse/HIVE-1841 > Project: Hive > Issue Type: Improvement > Components: Configuration, Metastore > Affects Versions: 0.6.0 > Reporter: Edward Capriolo > Assignee: Ashutosh Chauhan > Priority: Minor > Labels: TODOC2.0 > Fix For: 2.0.0 > > Attachments: HIVE-1841.1.patch.txt, HIVE-1841.2.patch, HIVE-1841.patch > > > Two datanucleus variables: > {noformat} > <property> > <name>datanucleus.autoCreateSchema</name> > <value>false</value> > </property> > <property> > <name>datanucleus.fixedDatastore</name> > <value>true</value> > </property> > {noformat} > are dangerous. We do want the schema to auto-create itself, but we do not > want the schema to auto update itself. > Someone might accidentally point a trunk at the wrong meta-store and > unknowingly update. I believe we should set this to false and possibly trap > exceptions stemming from hive wanting to do any update. This way someone has > to actively acknowledge the update, by setting this to true and then starting > up hive, or leaving it false, removing schema modifies for the user that hive > usages, and doing all the time and doing the updates by hand. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
