[jira] [Commented] (YARN-4955) Add retry for SocketTimeoutException
in TimelineClient
[ https://issues.apache.org/jira/browse/YARN-4955?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15239541#comment-15239541 ]
Junping Du commented on YARN-4955:
----------------------------------
Thanks [~xgong] for reporting the issue and delivering the patch. The issue reported here is valid and I also see the same problem in some logs. For fix, I think we are missing the catch part:
{code}
public Object retryOn(TimelineClientRetryOp op)
throws RuntimeException, IOException {
int leftRetries = maxRetries;
retried = false;
// keep trying
while (true) {
try {
// try perform the op, if fail, keep retrying
return op.run();
} catch (IOException | RuntimeException e) {
// break if there's no retries left
{code}
As AuthenticationException is neither a IOException or RuntimeException, we will miss to catch here.
Can you add AuthenticationException in catch clause? Also, it would be nice if we can have a unit test to verify it works.
