MinJi Kim commented on CALCITE-1110: ------------------------------------ I am curious about what is being considered to resolve this issue. I am having similar issue with jackson/fasterxml that is being used in Drill. I have shaded the jackson packages in Avatica in my local build to move forward with what I am working on, so if it would help to upload this patch to start a discussion, I am more than happy to do so. Thanks! > remove or relocate shaded jackson in Avatica > -------------------------------------------- > > Key: CALCITE-1110 > URL: https://issues.apache.org/jira/browse/CALCITE-1110 > Project: Calcite > Issue Type: Improvement > Components: avatica > Affects Versions: 1.6.0, 1.5.0 > Reporter: Kai Gülzau > Assignee: Josh Elser > Priority: Critical > Fix For: avatica-1.9.0 > > > The avatica jar includes a shaded version of jackson under the original > package path. > This shaded version interferes with other jackson versions in the classpath. > Currently this prevents us from using jackson functionality which is only > implemented in newer versions. > https://mail-archives.apache.org/mod_mbox/calcite-dev/201602.mbox/%3C977C7450-18F4-48E2-A970-69B7E3E1BD2C%40apache.org%3E > {quote} > Is it reasonable to have a maven profile that uses jackson as “provided”[1] > rather than shading? This would not be the default — the default would be > continue to use a shaded version of jackson (relocated to > org.apache.calcite.jackson, as Josh suggests) — but folks looking to embed > calcite/avatica in a container might appreciate a lighter weight option. > {quote} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
