Hello Accumulo, Summary: commons-vfs2 version 2.2 seems to have problems and it may be worth rolling back to version 2.1 of commons-vfs2.
My project upgraded a system from Accumulo 1.8.1 to 1.9.2. Immediately after switching vfs contexts we saw problems. The tservers would error in iterators about missing classes that were clearly on the classpath. The problems were persistent until we replaced the commons-vfs2.jar with version 2.1 (Accumulo 1.9.2 uses version 2.2). Until we rolled vfs back, we received errors particularly with Spring code trying to access various classes and files within the jars. It looks like in 2.2, commons-vfs implemented a doDetach method which closed the zip files. We suspect that code is the problem but haven't tested that theory. I suspect that most users don't use this feature. Thanks! Matt
