Subject [jira] Commented: (HADOOP-1053) Make Record I/O usable from independent of Hadoop
Date Sat, 03 Mar 2007 01:43:50 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-1053?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12477579

David Bowen commented on HADOOP-1053:

> The three referenced o.a.h.io classes currently have no other dependencies.

I don't think that is true.  WritableComparator references DataInputBuffer, and WritableUtils
imports from other packages.

Even if it were true, it would be a fragile "solution" to the identified problem, since additional
dependencies will creep in over time.

> The stated goal "independent of Hadoop" is nonsensical, as record io is a part of hadoop.

Yes, we should rephrase it.  The goal is or was to make the record i/o functionality modular.
 I.e. there should be some identifiable (proper) subset of Hadoop which supports  the record
i/o functionality and can be used separately.  Clearly we do not have a consensus that this
is a worthwhile goal. If we did, I'm sure we could find a better solution, but given that
we don't, there isn't much point in wasting more time on it.

> This issue has been created to separate one proposal originally included in HADOOP-941,
for which no consensus could be reached. For earlier discussion about the issue, please see
> I will summarize the proposal here.  We need to provide a way for some users who want
to use record I/O framework outside of Hadoop.
