----------------------------------------
Summary: OpenKey logic issue
Key: HDDS-1664
URL: https://issues.apache.org/jira/browse/HDDS-1664
Project: Hadoop Distributed Data Store
Issue Type: Bug
Reporter: Bharat Viswanadham
In OpenKey, we first check bucket exists/volume exists then acquire lock.
There might be a case, like where we have checked for bucket, volume exists,
then there is in parallel a delete bucket operation acquired lock and deleted
bucket after our checks are done in openKey. Then once delete Bucket is done,
we release lock, and openKey acquires bucket lock, we might create an openKey
in a deleted bucket. If security is enabled, we might see NPE also for this.
I think we should check for bucket,volume exists once after acquiring the lock.
OpenKey.java:
Line 452:
OmBucketInfo bucketInfo = getBucketInfo(volumeName, bucketName);
encInfo = getFileEncryptionInfo(bucketInfo);
Line 2015:
private FileEncryptionInfo getFileEncryptionInfo(OmBucketInfo bucketInfo)
throws IOException {
FileEncryptionInfo encInfo = null;
BucketEncryptionKeyInfo ezInfo = bucketInfo.getEncryptionKeyInfo();
