Hi,
Just want to add on daemeon, if the miss configuration happened on couple of nodes. It's better to do it one at a time or else take backup of your data.

Then just restart hadoop. As long as this does not take too long, you don't have write consistency that forces that shard to be written, etc. you will be fine. Daemeon C.M.

To fix this, I presume I should decommission the relevant nodes, fix the mounts, then recommission the nodes. My question is, when the nodes are recommissioned, will the HDFS storage automatically be reset to ‘empty’, or do I need to perform some sort of explicit initialization on those volumes before returning the nodes to active status. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
