Dinesh S. Atreya commented on HDFS-9607: ---------------------------------------- What I meant to say is that users can exercise the liberty to copy a portion of the array and fill it with *_spaces_* for example; if users want to update/replace {noformat} "Hello HDFS" {noformat} with {noformat} "Hi HDFS" {noformat} they can do so using {{fill}} and {{copyOf}} methods from https://docs.oracle.com/javase/8/docs/api/java/util/Arrays.html. > Advance Hadoop Architecture (AHA) - HDFS Update (write-in-place) > ---------------------------------------------------------------- > > Key: HDFS-9607 > URL: https://issues.apache.org/jira/browse/HDFS-9607 > Project: Hadoop HDFS > Issue Type: New Feature > Reporter: Dinesh S.
