[jira] [Commented] (BEAM-8331) Vendored calcite breaks if another
calcite is on the class path
[ https://issues.apache.org/jira/browse/BEAM-8331?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16942970#comment-16942970 ]

---------------------------------------
[~vectorijk] would you be interested in doing this follow-up to the vendoring?

> If the beam vendored calcite and a non-vendored calcite are both on the classpath, neither version works. This is because the non-JDBC calcite path uses JDBC as a easy way to perform reflection. (This affects the non-JDBC version of calcite.) We need to rewrite the calcite JDBC urls as part of our vendoring (for example 'jdbc:calcite:' to 'jdbc:beam-vendor-calcite:'). Example of where this happens: [https://github.com/apache/calcite/blob/0cce229903a845a7b8ed36cf86d6078fd82d73d3/core/src/main/java/org/apache/calcite/tools/Frameworks.java#L175]
