[jira] [Commented] (KUDU-3022) C++ Client does not retry CreateTable on "new table name is already reserved" error

["Adar Dembo (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KUDU-3022?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16997642#comment-16997642 ] 

Adar Dembo commented on KUDU-3022:
----------------------------------

This is also an issue for altering a table.

LookupRpc::SendRpcCb has the following code; maybe it needs to be pushed into AsyncLeaderMasterRpc::RetryOrReconnectIfNecessary?
{noformat}
  // Check for more application errors.
  // Note: RetryOrReconnectIfNecessary only checked for generic application
  // errors. This check is specific to LookupRpc.
  if (new_status.ok() && resp_.has_error()) {
    new_status = StatusFromPB(resp_.error().status());
    if (new_status.IsServiceUnavailable()) {
      // One or more of the tablets is not running. Retry after some time.
      mutable_retrier()->DelayedRetry(this, new_status);
      ignore_result(delete_me.release());
      return;
    }
  }
 {noformat}

> If two callers try to create a table with the same name at the same time, one of them can fail with the error: "new table name foo is already reserved". The comments in catalog_manager.cc seem to indicate that this should trigger the client to retry, but it seems the retry is not taking place.
