> java.io.IOException: cannot get log writer

>       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.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.
