Check Point query

If a file is being copied (let’s say 100GB ) to HDFS and the check point time arrives(assume it happens after every one hour), then the data that’s being transferred, will it be aborted, paused or the check point will be delayed as during checkpoint HDFS enters safe mode(read only mode) and no data transfer is allowed at that moment.

@arburra, that’s why we have ‘distcp’ option to copy huge files in distributed manner.
