I checked the heap of the namenode and there is no problem (I have 75 GB of max heap, I'm around 50 used GB).    Why 75GB heap size for NN? are you running a very large cluster?    50 GB of heap used? Can you check are talking about the NN heap itself or are you saying about the total mem

your observation is correct. backup node will also download. If you look at the journey/evolution of hadoop, we had primary, backup only, checkpointing node and then a generic secondary node. checking node will do the merge of fsimage and edits On 25/9/17 5:57 pm, Chang.Wu wrote: From the

400GB as heap space for Namenode is bit high. The GC pause time will be very high. For a cluster with about 6PB, approx 20GB is decent memory. As you mentioned it is HA, so it is safe to assume that the fsimage is check pointed at regular intervals and we do not need to worry during a manual
