I just saw another error after my job was run for 2 hours:
org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.hdfs.server.namenode.LeaseExpiredException):
No lease on /apps/data/vddil/real-time/checkpoint/temp: File does not
exist. Holder DFSClient_NONMAPREDUCE_327993456_13 does not have any
open files.

14/07/25 14:45:12 WARN CheckpointWriter: Error in attempt 1 of writing
checkpoint to
hdfs://gnosis-01-01-01.crl.samsung.com/apps/data/vddil/real-time/checkpoint/checkpoint-1406324700000
All my jobs use the same parameter to the function checkpoint. Is it the
reason for the error?
I will post the stack trace of the other error after it appears again.
Thanks!
