Namenode Heap is gradually increasing and failover to SNN

New Contributor

Hello,

 

   Cluster Namenode size is gradually increasing (1-2GB) everyday and it is hitting the high mark. Because of this there is a frequent failover happening on the cluster. Would it be possible to find out what is causing this? Is only number of blocks that is the reason for this issue? Because sometimes the number of blocks count is same but still Heap is keep on increasing. What steps need to be taken to stop this behaviour?

 

Heap size:135GB

Total Files: 130M and Total Blocks:130M

 

Thanks
