-----------------------------------------
Summary: Conditional error in SENTRY-1931 results in sending two
snapshots at the same time
Key: SENTRY-1946
URL: https://issues.apache.org/jira/browse/SENTRY-1946
Project: Sentry
Issue Type: Bug
Affects Versions: 2.0.0
Reporter: Vamsee Yarlagadda
Assignee: Vamsee Yarlagadda
As part of SENTRY-1931, we added check not to send two NN snaphsots at the same
time. But because of a conditional typo, it results in sending back two
snapshots.
{code}
// If another paths updates request is in progress by another HDFS
NameNode, then we
// return an empty image for now to avoid a large memory consumption
if (pathsRetrieverBusy.compareAndSet(false, true)) {
LOGGER.debug("PATHS updates are not available because another request is
in progress.");
return Collections.emptyList();
}
{code}
