> The following can be observed running against hadoop3:
> {code}
> java.io.IOException: cannot get log writer
> 	at org.apache.hadoop.hbase.regionserver.TestCompactingMemStore.compactingSetUp(TestCompactingMemStore.java:107)
> 	at org.apache.hadoop.hbase.regionserver.TestCompactingMemStore.setUp(TestCompactingMemStore.java:89)
> Caused by: org.apache.hadoop.hbase.util.CommonFSUtils$StreamLacksCapabilityException:
hflush and hsync
> 	at org.apache.hadoop.hbase.regionserver.TestCompactingMemStore.compactingSetUp(TestCompactingMemStore.java:107)
> 	at 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.
