Ewan Higgs commented on HDFS-10675: ----------------------------------- {quote} The proposal to handle this is to change the return type of the above functions to Optional<File>. This will lead to changes in a lot of other places but will make it explicit that the return value can be null. I propose to open a new JIRA for this. {quote} Hi [~virajith]. I think this makes sense as it keeps the patches specific to the thing they are trying to solve. Would you like to create the ticket under HDFS-9806? > Datanode support to read from external stores. > ----------------------------------------------- > > Key: HDFS-10675 > URL: https://issues.apache.org/jira/browse/HDFS-10675 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Virajith Jalaparti > Attachments: HDFS-10675-HDFS-9806.001.patch, > HDFS-10675-HDFS-9806.002.patch, HDFS-10675-HDFS-9806.003.patch > > > This JIRA introduces a new {{PROVIDED}} {{StorageType}} to represent external > stores, along with enabling the Datanode to read from such stores using a > {{ProvidedReplica}} and a {{ProvidedVolume}}. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
