Connect to Impala with LDAP authentication

Anonymous — Sat, 16 Nov 2024 11:06:57 GMT

Hi,
Has anybody able to connect to Impala with native connector to the cluster which has LDAP security? As per my understanding currently uri of impala connection have hardcoded value "auth=noSasl" which is used only if cluster does not have security. To connect to LDAP secured cluster uri should pass parameter "AuthMech=3", but there is no such option.
p.s Talend promotes its big data appliance and is a partner of cloudera, but does not support such important functionality.
p.s2 I know that it is possible to set up custom JDBC connection, but i want native impala connector to work as it should.

It should be fairly trivial to edit the tImapalaConnection template (look in ${TALEND_HOME}/plugins/org.talend.designer.components.bigdata_${VERSION}/components) and add an additional dropdown "AuthMec" to the component and remove the 'noSasl' string. See if you can find a tutorial like http://www.talendforge.org/wiki/doku.php?id=doc:component_creation_example_java to show you how to edit a component.
