    Hi all,

    Now we can create snapshots on the HDFS directory. I am curious how HDFS handle the disk full error when creating a new snapshot. I guess there are two options
    1: Report IODiskFull exception during creating new snapshot.
    2: Automatically delete the oldest file or snapshot files, then create the new snapshot successfully.

    By the way, how HDFS handle the disk full error when putting new files to HDFS?

    Thanks,
    Jack Chen

    Hi Jack,
    An error should occur when trying to put a file to full cluster. Since HDFS is scalable, Adding a new node would be the suggestion to do as you reach your capacity.
