---------------------------------------
Running:
{noformat}
./bin/accumulo org.apache.accumulo.server.fate.Admin print
{noformat}
often fails with a NoNode exception during the random walk test.

> Key: ACCUMULO-1233
> URL: https://issues.apache.org/jira/browse/ACCUMULO-1233
> Project: Accumulo
> Issue Type: Bug
> Components: master, tserver
> Reporter: Eric Newton
> Assignee: Eric Newton
> Priority: Minor
> Labels: 15_qa_bug
> Fix For: 1.5.0
>
>
> There's a common pattern used with zookeeper:
> {noformat}
> for (String child : zk.getChildren(path)) {
> byte[] content = zk.getData(path + "/" + child, null, null);
> doSomething(content);
> }
> {noformat}
> The problem is that between the getChildren() call and the getData() call,
> the child node has gone away.
> We'll typically retry these operations, but it puts big scary messages in the
> logs.
