how to re-create the fsimage_xxxxxxx files on namenode

[#1]

we have two namenode machines ( are part of HDP cluster in ambari )

because electricity failure , we notices about the following

on one name node we see that fsimage_xxxx files are missing
while on the second namenode they are exists

is it possible to re-create them on the faulty name node

example on the bad node

ls /hadoop/hdfs/namenode/current | grep fsimage_

no output

on the good namenode

ls /hadoop/hdfs/namenode/current | grep fsimage_
fsimage_0000000000044556627
fsimage_0000000000044556627.md5
fsimage_0000000000044577059
fsimage_0000000000044577059.md5

the status for now is that name-node service not startup successfully from ambari

and the logs from the faulty name-node say like this:

ERROR namenode.NameNode (NameNode.java:main(1783)) - Failed to start namenode.
java.io.FileNotFoundException: No valid image files found

Dear Shelton

this is very very strange that some application / other delete the files ( there are 4 files while 2 of them represented the md5 chksum )

what we are very worry from this case , is that we actuality not know the real reason why files deleted 

and we cant reverse and see whats happens
