Ted Yu commented on HBASE-17182:
--------------------------------

{code}
+  public void testCleanScannerThread() throws Exception {
{code}
Rename the test method.
{code}
+        } catch (InterruptedException e) {
+          // LOG.error(e);
{code}
Restore interrupt status.
{code}
+              // ResultScanner scanner = scannerInfo.getScanner();
+              // scanner.close(); // Close will throw UnknownScannerException
{code}
You can drop the above lines.
