------------------------------------
Summary: Race condition in TestRetryCacheWithHA#testCreateSymlink
causes spurious test failure
Key: HDFS-5289
URL: https://issues.apache.org/jira/browse/HDFS-5289
Project: Hadoop HDFS
Issue Type: Bug
Components: test
Affects Versions: 2.1.1-beta
Reporter: Aaron T. Myers
Assignee: Aaron T. Myers
The code to check if the operation has been completed on the active NN can
potentially execute before the thread actually doing the operation has run. In
this case the checking code will retry the check if the result of the check is
null. However, the test operation does not in fact return null, instead
throwing an exception if the file doesn't exist yet. We need to catch the
exception and retry.
