[jira] [Created] (HADOOP-15149) CryptoOutputStream doesn't implement StreamCapabilities

Mike Drob created HADOOP-15149:
----------------------------------

             Summary: CryptoOutputStream doesn't implement StreamCapabilities
                 Key: HADOOP-15149
                 URL: https://issues.apache.org/jira/browse/HADOOP-15149
             Project: Hadoop Common
          Issue Type: Task
          Components: fs
    Affects Versions: 3.0.0
            Reporter: Mike Drob


Running some tests with HBase on HDFS with encryption, we noticed that CryptoOutputStream doesn't implement StreamCapabilities.

Specifically, we have a HdfsDataOutputStream wrapping a CryptoOutputStream. The calls to {{hasCapability}} on the HDOS will always return false, even though the COS could be wrapping something that supports it, as evidenced by the implementation of hsync and hflush here.
