Mike Drob commented on HBASE-19841:
-----------------------------------
v4 passed all tests against an older master, I'm rebased and running tests
again locally now.
It removes the property from hbase-site.xml and moves it to HTU.createLocalHTU.
This is good because it actually exposes it for downstream consumers who may be
using our test code to do their own thing and will just do the right thing for
them most of the time. A further improvement would be to remove the distinction
between a local and cluster based HTU, make it local until somebody starts a
DFS cluster then reconfigure everything. shouldn't be much of a performance
impact and will be much easier for folks to use.

> org.apache.hadoop.hbase.regionserver.TestCompactingMemStore.setUp(TestCompactingMemStore.java:89)
> {code}
> This was due to hbase-server/src/test/resources/hbase-site.xml not being
> picked up by Configuration object. Among the configs from this file, the
> value for "hbase.unsafe.stream.capability.enforce" relaxes check for presence
> of hflush and hsync. Without this config entry,
> StreamLacksCapabilityException is thrown.
