Yongjun Zhang created HDFS-11799: ------------------------------------ Summary: Introduce a config to allow setting up write pipeline with single node Key: HDFS-11799 URL: https://issues.apache.org/jira/browse/HDFS-11799 Project: Hadoop HDFS Issue Type: Bug Reporter: Yongjun Zhang
During pipeline recovery, if not enough DNs can be found, if dfs.client.block.write.replace-datanode-on-failure.best-effort is enabled, we let the pipeline to continue, even if there is a single DN. Similarly, when we create the write pipeline initially, if for some reason we can't find enough DNs, we can have a similar config to enable writing with a single DN. More study will be done. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
