[jira] [Created] (ACCUMULO-635) Check Existence of Zookeeper
Recovery Node Before Reading It.
David Medinets created ACCUMULO-635:
---------------------------------------
Summary: Check Existence of Zookeeper Recovery Node Before Reading It.
Key: ACCUMULO-635
URL: https://issues.apache.org/jira/browse/ACCUMULO-635
Project: Accumulo
Issue Type: Bug
Reporter: David Medinets
Assignee: David Medinets
Priority: Minor
I don't know why but my errors have started to display the following message. I tracked down the source. Basically the Zookeeper node is being read without first making sure that it exists.
{code}
org.apache.zookeeper.KeeperException$NoNodeException: KeeperErrorCode

ZooReaderWriter.getInstance().getChildren(zroot + Constants.ZRECOVERY, new Watcher() {
@Override

---------------------------------------
I made a change to create the node in zookeeper when init is run. I still need to create the node when upgrading from 1.4 to 1.5
