Nanda kumar updated HDDS-271: ----------------------------- Comment: was deleted (was: As this is an iterator we can throw NoSuchElementException if the iteration has no more element instead of returning null. If {{hasNext}} returns true we should be able to return the next block on {{nextBlock}} call. Consider a case where we have two blocks [key1:block1, #deleting#key2:block2]. For the first {{hasNext}} call we will return {{true}} and the {{nextBlock}} call will return key1:block1. For the second {{hasNext}} call we will return {{true}} but the {{nextBlock}} call will return {{null}}. This will create inconsistent behavior in code wherever the iterator is used. We cannot fully rely on {{hasNext}} call anymore.) > Create a block iterator to iterate blocks in a container > -------------------------------------------------------- > > Key: HDDS-271 > URL: https://issues.apache.org/jira/browse/HDDS-271 > Project: Hadoop Distributed Data Store > Issue Type: Improvement > Reporter: Bharat Viswanadham > Assignee: Bharat Viswanadham > Priority: Major > Fix For: 0.2.1 > > Attachments: HDDS-271.00.patch, HDDS-271.01.patch, HDDS-271.02.patch, > HDDS-271.03.patch > > > Create a block iterator to scan all blocks in a container. > This one will be useful during implementation of container scanner. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
