    [ https://issues.apache.org/jira/browse/HBASE-8034?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13597369#comment-13597369 ] 

Nick Dimiduk commented on HBASE-8034:
-------------------------------------

Would it make more sense to expose the number of KeyValues in the HFile?

{code}
+  @Override
+  public long getCurrentSize() throws IOException {
+    if (this.outputStream == null) return -1;
+    return this.outputStream.getPos();
+  }
{code}

This strikes me as flakey. Will there be another thread writing to the OutputStream when this method is invoked? Should it be synchronized?
