After upgrading to BDA V4.7, V4.8 or V4.9 connectivity issues between nodes are intermittently seen in Cloudera Manager(CM). This may result in CM alerts and services going down. It may also result in missing data blocks.
At the same time as the connectivity issues it is observed that the IPoIB interface is down as observed by ip ping between nodes failing while ibping is successful. The external EoIP interface is up. Nodes can self-ping with ip ping but ip ping between nodes fails. The IB fabric is confirmed to be fully healthy.
