Review comment:
Hey @bharatviswa504
Seems this NPE in S3G occurred again, I got some clue, but haven't found the
root cause yet.
OM side, `S3MultipartUploadCommitPartRequest` failed due to upload id not
found.
S3G side,
```
} finally {
IOUtils.closeQuietly(ozoneOutputStream);
}
```
`OzoneOutputStream.close()` will call `OmMultipartCommitUploadPartInfo
commitMultipartUploadPart(
OmKeyArgs omKeyArgs, long clientID) throws IOException;` to commit the
key, but `IOUtils.closeQuietly()` will swallow IOException that relates to this
error, thus
```
OmMultipartCommitUploadPartInfo omMultipartCommitUploadPartInfo =
ozoneOutputStream.getCommitUploadPartInfo();
```
will return null, trigger the NPE issue.

How about we avoid call `IOUtils.closeQuietly(ozoneOutputStream);` to throw
out the `NO_SUCH_MULTIPART_UPLOAD_ERROR` ?
