hanishakoneru opened a new pull request #450: HDDS-2893. Handle replay of KeyPurge Request. URL: https://github.com/apache/hadoop-ozone/pull/450 ## What changes were proposed in this pull request? If KeyPurgeRequest is replayed, we do not want to purge the keys which were created after the original purge request was received. This could happen if a key was deleted, purged and then created and deleted again. The the purge request was replayed, it would purge the key deleted after the original purge request was completed. Hence, to maintain idempotence, we should only purge those keys from DeletedKeys table that have updateID < transactionLogIndex of the request. ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-2893 ## How was this patch tested? Unit test will be added in next commit
