Hi all, I'm facing an issue with HDFS 3.3.5 cluster.I have created a total of 650 files with replication set to 1 and block size set to 4MB and each file size is 4MB which should result in a subtotal of 2.5GB, but the storage utilisation is marked closer to 100% due to this. Thanks.

How does the ZKFC running in the namenode server maintain a open session in zookeeper?

Hi @Majeti , Thanks for your response. 2. This merging process happens in memory each time, ensuring that the namespace stays up-to-date with the latest changes. In this step you have mentioned merging process, how that merging process is happening between edit logs and old fsimage ?

I have seen this post, I understood how the flow is happening, but how the edit logs transactions are applied to fsimage is not mentioned. Can you please clear that ? And also, how block report is generated in datanode and how it is handled in namenode side?

@VidyaSargur Thanks. @Asok @willx Can you please help me with how the transactions in edit logs are applied to fsimage in Standby namenode ?
