Masatake Iwasaki commented on HDFS-10367:
-----------------------------------------

Thanks for the update, [~brahmareddy].

{code}
+      } else {
+        Thread.sleep(1000);
+        tries++;
+        if (tries >= retries) {
+          throw new IOException(
+              "Port is already in use; giving up after " + tries + " times.");
+        }
+      }
{code}

should check {{tries}} before sleeping. I'm +1 if this is addressed.
