Atreya commented on HDFS-9607: ---------------------------------------- Personal preference regarding API naming. * We can prefer to use "writeInPlace" for the method name (as it is descriptive). Welcome other suggestions. * We can have auxiliary methods "updtInPlace" and "deleteInPlace" which will be no-ops performing the check "checkWriteInPlace" or calling "writeInPlace". The Hadoop sub-systems such as ORC, HIVE, etc. may then override "updtInPlace" and "deleteInPlace" methods to implement functionality relevant to each. > Advance Hadoop Architecture (AHA) - HDFS > ---------------------------------------- > > Key: HDFS-9607 > URL: https://issues.apache.org/jira/browse/HDFS-9607 > Project: Hadoop HDFS > Issue Type: New Feature > Reporter: Dinesh S.
