[jira] [Created] (KUDU-1559) blocks_open_writing metric shows thousands of blocks open at once

             Summary: blocks_open_writing metric shows thousands of blocks open at once
                 Key: KUDU-1559
                 URL: https://issues.apache.org/jira/browse/KUDU-1559
             Project: Kudu
          Issue Type: Bug
          Components: fs, tserver
    Affects Versions: 0.10.0
            Reporter: Todd Lipcon


The 'block_manager_blocks_open_writing' metric is showing tens of thousands of blocks open for write on my tservers in a test cluster. That seems incorrect to me, since we should only have blocks open in the middle of a flush. Perhaps the metric is wrong, or perhaps we are somehow leaking open blocks.
