ATTACHMENT ID: 12690657 - PreCommit-HIVE-TRUNK-Build > HMS on Oracle incompatibility > ----------------------------- > > Key: HIVE-8485 > URL: https://issues.apache.org/jira/browse/HIVE-8485 > Project: Hive > Issue Type: Bug > Components: Metastore > Environment: Oracle as metastore DB > Reporter: Ryan Pridgeon > Assignee: Chaoyu Tang > Attachments: HIVE-8485.2.patch, HIVE-8485.patch > > > Oracle does not distinguish between empty strings and NULL,which proves > problematic for DataNucleus. > In the event a user creates a table with some property stored as an empty > string the table will no longer be accessible. > i.e. TBLPROPERTIES ('serialization.null.format'='') > If they try to select, describe, drop, etc the client prints the following > exception. > ERROR ql.Driver: FAILED: SemanticException [Error 10001]: Table not found > <table name> > The work around for this was to go into the hive metastore on the Oracle > database and replace NULL with some other string. Users could then drop the > tables or alter their data to use the new null format they just set. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
