Is it the change outlined in the attached proposal or the build/distro restructure? This bug is currently a blocker for the Solaris DomainSocket timeout work, which is in turn implicated in a large number of Solaris test bugs. Until we can establish what the way forward is, even if that's only an interim solution, I'm pretty much dead in the water. > Improve versioning and compatibility support in native library for downstream hadoop-common users. > -------------------------------------------------------------------------------------------------- > > Key: HADOOP-11127 > URL: https://issues.apache.org/jira/browse/HADOOP-11127 > Project: Hadoop Common > Issue Type: Bug > Components: native > Reporter: Chris Nauroth > Assignee: Alan Burlison > Attachments: HADOOP-11064.003.patch, proposal.01.txt > > > There is no compatibility policy enforced on the JNI function signatures implemented in the native library. This library typically is deployed to all nodes in a cluster, built from a specific source code version. However, downstream applications that want to run in that cluster might choose to bundle a hadoop-common jar at a different version. Since there is no compatibility policy, this can cause link errors at runtime when the native function signatures expected by hadoop-common.jar do not exist in libhadoop.so/hadoop.dll. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
