[jira] [Updated] (HIVE-22488) Break up DDLSemanticAnalyzer -
extract Table creation analyzers
[ https://issues.apache.org/jira/browse/HIVE-22488?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Miklos Gergely updated HIVE-22488:
----------------------------------
Description:
DDLSemanticAnalyzer is a huge class, more than 4000 lines long. The goal is to refactor it in order to have everything cut into more handleable classes under the packageĀ org.apache.hadoop.hive.ql.exec.ddl:
* have a separate class for each analyzers
* have a package for each operation, containing an analyzer, a description, and an operation, so the amount of classes under a package is more manageable
Step #9: extract the table creationanalyzers from DDLSemanticAnalyzer, and move them under the new package.

Step #8: extract all the rest of the analyzers from DDLSemanticAnalyzer, which can not be classified otherwise, and move them under the new package.
