Re: Journal Node Sync - moving to new machine

Hi Kartik,

Have you tried following these steps:

Otherwise, if you can bring down HDFS, you can do the following:

1. Stop HDFS service

2. Copy over JN edits from a (good) JN to the (bad) JN. Make sure you get all edits from all dirs (

dfs.journalnode.edits.dir)
3. Start HDFS service
 
Let me know if that works for you.
