> Components: Hdfs Plugin
> Affects Versions: 1.7.0
> Reporter: Sravya Tirukkovalur

> Right now if there is an error condition in evaluating paths in MetastoreCacheInitializer in one of the tasks, we throw a Runtime Exception (in Sentry-888). Changed the behavior to be:
> * Retry the failed tasks x times. Each retry has a y millis wait duration. x and y are based upon the user config (sentry.hdfs.sync.metastore.cache.retry.max.num and sentry.hdfs.sync.metastore.cache.retry.wait.duration.millis).
> * After retry failure, throw exception or sync incomplete paths update based on user config (sentry.hdfs.sync.metastore.cache.fail.on.partial.update). The default values is fail on partial update, which will throw runtime exception.
> {noformat}
> for (Future<CallResult> result : results) {
> CallResult callResult = result.get();
> // Fail the HMS startup if tasks are not all successful and
> // fail on partial updates flag is set in the config.
> if (callResult.getSuccessStatus() == false && failOnRetry) {
> throw new RuntimeException(callResult.getFailure());
> }
> }
> {noformat}
