Bogdan Raducanu reassigned HDFS-7268: ------------------------------------- Assignee: (was: Bogdan Raducanu) > Can't append with SYNC_BLOCK > ---------------------------- > > Key: HDFS-7268 > URL: https://issues.apache.org/jira/browse/HDFS-7268 > Project: Hadoop HDFS > Issue Type: Bug > Components: hdfs-client > Affects Versions: 2.4.1 > Reporter: Bogdan Raducanu > > It seems to me that currently it's not possible to start appending to a file > with CreateFlag.SYNC_BLOCK behavior (i.e. hsync after each block). So, I > think, the only way to guarantee durability when appending is if the user > calls hsync at the end of each block. > FileSystem.append doesn't accept a CreateFlag argument. > FileSystem.create, on the other hand, ignores CreateFlag.APPEND afaics. I > think the plan in HDFS-744 was to use this method if durability is needed. > It seems it might work through FileContext but in the end DFSOutputStream > never sets shouldSyncBlock when appending anyway. > Or am I missing something? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
