I report the same situation as comment 129. Spark Cluster installed with Ambari 1.7, installed HDP 2.2 running Zookeeper, Ganglia, HDFS and YARN. Ubuntu 12.04
uname -r 3.2.0-67-virtual Instances running fine until the start of a Spark of Hadoop job with YARN. The Job gets accepted but then 2 slaves of the cluster are interested by the bug and lose connectivity. They are still accessible by the openstack web page console but can't reach the network. Reboots brings the VM in a halt state. Solved with ethtool -K eth0 tx off sg off tso off ufo off gso off gro off lro off -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/997978 Title: KVM images lose connectivity with bridged network To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/997978/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
