NameNode in unknown state

New Contributor

Hi Team,

 

kindly note that I have 16 nodes of hadoop where node1 and node2 are the OAM and the rest is processing hadoop nodes on cloudera 4. 

 

unfortuntley, for OAM node2, the name node is not able to recover as shown below:

 

--INFO---- sbf-in-ed2 - 2022-04-12 16:54:23 - Call: recover_namenode() detect
--INFO---- sbf-in-ed2 - 2022-04-12 16:54:34 - recover_namenode(): This is a name node in unknown state

 

could you please help on this subject?

 

Appreciate your feedback.. 

 

Thanks
