Tsz Wo (Nicholas), SZE commented on HADOOP-3534:
------------------------------------------------
In HADOOP-3509, I did the following change
{code}
- try {
- dir.close();
- } catch (IOException ex) {
- // do nothing
- }
+ IOUtils.close(LOG, dir);
{code}
Before HADOOP-3509, it formally ignores the IOException. I think it is good to
log the exception, at least for debug.
How should we handle the exception in close?
