At the beginning of a local checkpoint, each data node marks its local tables with a “to be checkpointed” flag. A failure of the master node during this process could cause either the LCP to hang, or one or more data nodes to be forcibly shut down. (Bug #13436481)
A node failure while a
ANALYZE TABLEstatement was executing resulted in a hung connection (and the user was not informed of any error that would cause this to happen). (Bug #13416603)

Rowscount in the output of
