Hi Tony, all, just tried to test elasticsearch on a very small (hence i386) debian system and obviously hit this issue. Digging into it just a very little bit, I tested with a downgraded version of libjackson2-dataformat-yaml with no success. So is that NoClassDefFoundError really related to the 2.7 version of libjackson2-dataformat-yaml? Is there any information about what the patch being currently developed will change? some environment information:
