[jira] [Created] (HBASE-18784) Use of filesystem that requires hflush / hsync / append / etc should query outputstream capabilities

Sean Busbey created HBASE-18784:
-----------------------------------

             Summary: Use of filesystem that requires hflush / hsync / append / etc should query outputstream capabilities
                 Key: HBASE-18784
                 URL: https://issues.apache.org/jira/browse/HBASE-18784
             Project: HBase
          Issue Type: Improvement
          Components: Filesystem Integration
    Affects Versions: 2.0.0-alpha-2, 1.4.0
            Reporter: Sean Busbey
            Assignee: Sean Busbey
            Priority: Blocker
             Fix For: 2.1.0, 1.5.0


In places where we rely on the underlying filesystem holding up the promises of hflush/hsync (most importantly the WAL), we should use the new interfaces provided by HDFS-11644 to fail loudly when they are not present (e.g. on S3, on EC mounts, etc).
