ZKUtil doesn't handle deleteRecurisively cleanly
------------------------------------------------
Key: HBASE-5775
URL: https://issues.apache.org/jira/browse/HBASE-5775
Project: HBase
Issue Type: Improvement
Affects Versions: 0.94.0
Reporter: Jesse Yates
Assignee: Jesse Yates
Fix For: 0.94.0, 0.96.0
ZKUtil.deleteNodeRecursively()'s contract says that it handles deletion of the
node and all its children. However, nothing is mentioned as to what happens if
the node you are attempting to delete doesn't actually exist. Turns out, it
throws a null pointer exception. I
'm proposing that we change the code s.t. it handles the case where the parent
is already gone and exits cleanly, rather than failing horribly.
