-------------------------------

             Summary: HiveKVResultCache.setupOutput hangs when the file creation failed
                 Key: HIVE-19406
                 URL: https://issues.apache.org/jira/browse/HIVE-19406
             Project: Hive
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.3.2
            Reporter: John Doe


The while loop in the HiveKVResultCache.setupOutput function hangs endlessly when the file creation failed, causing the delete() returns false.

The file creation failure can be caused by different reasons, e.g., disk full.

Here is the code snippet.

 
{code:java}
  private void setupOutput() throws IOException {
    if (parentFile == null) {
      while (true) {
        parentFile = File.createTempFile("hive-resultcache", "");
        if (parentFile.delete() && parentFile.mkdir()) {
          parentFile.deleteOnExit();
          break;
        }
        if (LOG.isDebugEnabled()) {
          LOG.debug("Retry creating tmp result-cache directory...");
        }
      }
    }
    ...
  }
{code}
