> Setting dfs.mover.retry.max.attempts to negative value will retry forever.
> --------------------------------------------------------------------------
>
> Key: HDFS-15439
> URL: https://issues.apache.org/jira/browse/HDFS-15439
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: balancer & mover
> Reporter: AMC-team
> Priority: Major
> Attachments: HDFS-15439.000.patch
>
>
> Configuration parameter "dfs.mover.retry.max.attempts" is to define the
> maximum number of retries before the mover consider the move failed. There is
> no checking code so this parameter can accept any int value.
> Theoratically, setting this value to <=0 should mean that no retry at all.
> However, if you set the value to negative value. The checking condition for
> retry failed will never satisfied because the if statement is "*if
> (retryCount.get() == retryMaxAttempts)*". The retry count will always +1 by
> retryCount.incrementAndGet() after failed but never *=* *retryMaxAttempts.*
> {code:java}
> private Result processNamespace() throws IOException {
> ... //wait for pending move to finish and retry the failed migration
> if (hasFailed && !hasSuccess) {
> if (retryCount.get() == retryMaxAttempts) {
> result.setRetryFailed();
> LOG.error("Failed to move some block's after "
> + retryMaxAttempts + " retries.");
> return result;
> } else {
> retryCount.incrementAndGet();
> }
> } else {
> // Reset retry count if no failure.
> retryCount.set(0);
> }
> ...
> }
> {code}
> *How to fix*
> Add checking code of "dfs.mover.retry.max.attempts" to accept only
> non-negative value or change the if statement condition when retry count
> exceeds max attempts.
