John Doe created HIVE-19406:
-------------------------------
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}
