Sean Busbey reopened HBASE-24086:
---------------------------------
I am -1 on this change and intend to revert it and the follow-on docs change so
that we can first have a discussion here or on dev@.
I am concerned that this went in without an in depth reconsideration of the
issues that come with trying to run against LocalFileSystem discussed in
HBASE-20354 (where the docs you changed were added) or HBASE-19289 (where the
check failing on LocalFileSystem first came up) or HBASE-21735 (where this
first showing up for Hadoop 2 came up when it was backported to HBase 1).
Furthermore you didn't ping any of the folks involved in any of those
discussion.
The point of requiring this change is in the config name and emphasizing it is
_unsafe_. A WARN message in a log is too easy to miss. Folks should not be
running a production instance against a local filesystem unless they affirm
they know what they are doing by setting that configuration value.
