Josh Elser commented on HBASE-19289:
------------------------------------
bq. put the property in test/resources/hbase-site.xml
That's a nice trick!
{code}
<description>We don't need to enforce stream capabilities in tests using local
FS</description>
{code}
How about instead: "Controls whether or not HBase will require stream
capabilities (hflush) in tests using the LocalFileSystem class".
Nit: TestHStore.java has a whitespace-only change.
bq. AFAICT anybody starting HBase on local file system is going to run straight
into a brick wall.
Need to return to this too, eh? The
[book|https://hbase.apache.org/book.html#_get_started_with_hbase] does have
instructions for users to create an hbase-site.xml -- is updating this
sufficient? A release note is obviously good to warn users. Is the error
message a user would find if they _didn't_ set this property sufficient to lead
them to somewhere that will clearly show them how to fix the problem (e.g. via
a web-search)?
