A table is only upgraded if it is white listed based > on the following new config property: phoenix.client.autoUpgradeWhiteList > If this property is not present, no tables will be upgraded. The config > property may have the following values: > - * which means upgrade everything or > - a comma separated list of fully qualified, case sensitive names (note that > by default, Phoenix stores table names in uppercase unless put them in double > quotes at DDL time) > Examples: > {code} > <property> > <name>phoenix.client.autoUpgradeWhiteList</name> > <value>*</value> <!- will upgrade all tables -> > </property> > {code} > {code} > <property> > <name>phoenix.client.autoUpgradeWhiteList</name> > <value>MY_SCHEMA.MY_TABLE, OTHER_TABLE</value> > </property> > {code} > The upgrade is only run once per connection to a cluster (when the > SYSTEM.CATALOG is created). If you need to force it to run again after that, > you can remove or set to "false" the UpgradeTo30 value that's stored in the > metadata of the SYSTEM.CATALOG table. -- This message was sent by Atlassian JIRA (v6.2#6252)
