> 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.
