Summary: Asyncfs should retry upon RetryStartFileException Key: HBASE-20686 URL: https://issues.apache.org/jira/browse/HBASE-20686 Project: HBase Issue Type: Bug 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 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)
