How to stop the namenode format scheduled

Expert Contributor

Hi All,

I ran a hdfs namenode metadataVersion command which inturn gave me a shocking output stating it would delete the blocks like in the below output.

I ran from Standby namenode, it scheduled after an hour. Im not sure it will delete actual hdfs metadata and make a full data loss or it is just compare active namenode and will delete only unwanted blocks on standby name node? before that i ran hdfs dfsadmin -report and there are no corrupted blocks. Before 10 mins of schedule i stopped all the primary and secondary cluster services and all datanode services on datanode. Kindly help it is urgent.

1. If i start namenode still it will start that schedule for deleting blocks or not?

2. Or Before starting the service how to check and disable that schedule?

output is attached.

NN2 - active, NN1 - Standby

$ hdfs namenode -metadataVersion

This is a normal log whenever the BlockManager starts up. You can even check it in the namenode logs. Invalid blocks such as overreplicated blocks if they exist will be deleted one hour after Namenode starts. No need to worry about any data loss here at all. Start your HDFS service as usual.

Hi Tarun, thanks for the reply. It helped and gave confidence. We simulated the same in development and upon confirmation we went ahead with production.

I was surprised to see the namenode service on standby NN getting restarted when we run this metadataVersion command. I feel this was just an informational command & the output was quite similar to namenode format command though it takes arguement as metadataversion. Hortonworks should have improved the output descriptions instead of just being general like "Block deletion will happen in 1 hr" (atleast they can put like only corrupted block deletion). Also unsure why it is restarting the namenode service which inturn takes the "dfs.namenode.startup.delay.block.deletion.sec" parameter and displays those information.
