ZanderXu created HDFS-16754: ------------------------------- Summary: UnderConstruct file with missingBlock should be able to recover lease Key: HDFS-16754 URL: https://issues.apache.org/jira/browse/HDFS-16754 Project: Hadoop HDFS Issue Type: Bug Reporter: ZanderXu Assignee: ZanderXu
During looking into the logic of RecoverLease, I guess there is a bug: {code:java} int nrCompleteBlocks; BlockInfo curBlock = null; for(nrCompleteBlocks = 0; nrCompleteBlocks < nrBlocks; nrCompleteBlocks++) { curBlock = blocks[nrCompleteBlocks]; if(!curBlock.isComplete()) break; // Why? assert blockManager.hasMinStorage(curBlock) : "A COMPLETE block is not minimally replicated in " + src; } {code} RecoverLease just try to align all replicas of the last block of one UnderConstruct file. So if the UC file with some completed blocks, which may missed all replicas, should be able to recoverLease. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
