---------------------------------------
> unhandled exception
> -------------------
>
> Key: HBASE-14399
> URL: https://issues.apache.org/jira/browse/HBASE-14399
> Project: HBase
> Issue Type: Bug
> Affects Versions: 1.0.1, 1.1.1, 1.0.1.1, 1.1.2
> Reporter: songwanging
> Priority: Minor
>
> In method run() of class HRegionServer(
> hbase-server\src\main\java\org\apache\hadoop\hbase\regionserver\HRegionServer.java).
> The first dummy catch block catch (KeeperException.NoNodeException nn)
> performs no actions to handle its expected exception, which makes itself
> useless.
> To fix this bug, developers should add more code into the catch block to
> handle this exception.
> public void run() {
> ...
> try {
> deleteMyEphemeralNode();
> }catch (KeeperException.NoNodeException nn){
> }catch (KeeperException e) {
> LOG.warn("Failed deleting my ephemeral node",e);
> }
> ...
> }
