Wei-Chiu Chuang updated HBASE-20686: ------------------------------------ Issue Type: Sub-task (was: Bug) Parent: HBASE-20898 > Asyncfs should retry upon RetryStartFileException > ------------------------------------------------- > > Key: HBASE-20686 > URL: https://issues.apache.org/jira/browse/HBASE-20686 > Project: HBase > Issue Type: Sub-task > Components: asyncclient > Affects Versions: 2.0.0-beta-1 > Environment: HBase 2.0, Hadoop 3 with at-rest encryption > Reporter: Wei-Chiu Chuang > Assignee: Wei-Chiu Chuang > Priority: Major > Attachments: HBASE-20686.master.001.patch, > HBASE-20686.master.002.patch > > > In Hadoop-2.6 and above, HDFS client retries on RetryStartFileException when > NameNode experience encryption zone related issue. The code exists in > DFSOutputStream#newStreamForCreate(). (HDFS-6970) > In HBase-2's asyncfs implementation, > FanOutOneBlockAsyncDFSOutputHelper#createOutput() is somewhat an imitation of > HDFS's DFSOutputStream#newStreamForCreate(). However it does not retry upon > RetryStartFileException. So it is less resilient to such issues. > Also, DFSOutputStream#newStreamForCreate() upwraps RemoteExceptions, but > asyncfs does not. Therefore, hbase gets different exceptions than before. > File this jira to get this corrected. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
