Hi Team,

Job failing due to below error, can any one help me on this.

Hi Team,

Any suggestions??

Hi @hanumanth There could be various factors that could cause such issues. 

Can you check what the Namenode was logging at the same time? 

It could be some Block Placement issue as the Datanodes are considered for the operation but something has restricted the write/read.

Hi all,

Issue has been resolved , while running job at staging level it requires more space in HDFS but no sufficient space in HDFS after added more disks , then job got success.
