[jira] [Updated] (SQOOP-2634) Sqoop2: Provide classpath isolation
for connectors and its dependencies
[ https://issues.apache.org/jira/browse/SQOOP-2634?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dian Fu updated SQOOP-2634:
---------------------------
Description:
The aim of this JIRA is to provide classpath isolation for connectors and its dependencies. It's achieved in the following method:
* Package connector jar with its dependencies. There will be a directory {{lib}} which contains the dependencies of the connector
* Improve the ConnectorClassLoader to make it can load classes from the dependencies which are inside the connector jar (SQOOP-2635)
* Load connector class with the connector's own ConnectorClassLoader.
was:Currently Sqoop 2 has already provided the ability to config jar dependencies with property "org.apache.sqoop.classpath.extra". The limitation of this property is that we have to put all the dependencies together. It can't express jar dependencies for a specified connector. This capacity is useful as some connectors may have conflict jar dependencies. Put all the dependencies from different connectors together may cause problems.
Summary: Sqoop2: Provide classpath isolation for connectors and its dependencies (was: Sqoop2: Allow connectors to express jar dependencies)
