You can grep for 'fsimage" or the "current" word so that if there is any entry for file deletion then it might be logged in there.

.

Also as it looks like your "fsimage" file is missing so i do not have any option right now to fix this issue until we have fsimage backup stored somewhere which we can restore. (Else we are in Data Loss Situation)

.

Is there any Mount point Or Filesystem issue which is causing the particular fsimage partition to go away (disappear) may be you can check with some storage guy to findout what happened to that file?

Re: JournalNode ( HDFS ) restarting all the time

@Jay is it possible to find other file fsimage from other cluster and use it on the problematic cluser ?

The fsimage file of one cluster can not be used on another cluster.
