Harmonize JAR library versions ------------------------------ Key: HADOOP-6800 URL: https://issues.apache.org/jira/browse/HADOOP-6800 Project: Hadoop Common Issue Type: Bug Reporter: Tom White Priority: Blocker Fix For: 0.21.0
Currently, multiple versions of the same library JAR are being pulled in for various reasons. * Within the same project, multiple versions of the same JAR are pulled in. E.g. Avro (used by Common) depends on Commons Lang 2.5 while Common depends on Commons Lang 2.4. * Dependent subprojects use different versions. E.g. Common depends on Avro 1.3.2 while MapReduce depends on 1.3.0. Since MapReduce depends on Common, this has the potential to cause a problem at runtime. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
