-----------------------------------------

             Summary: For shortcircuit reading, dfs.client.read.shortcircuit.skip.checksum does not take effect
                 Key: HADOOP-19749
                 URL: https://issues.apache.org/jira/browse/HADOOP-19749
             Project: Hadoop Common
          Issue Type: Bug
          Components: hdfs
    Affects Versions: 3.3.3
            Reporter: zhixingheyi-tian


For shortcircuit reading, dfs.client.read.shortcircuit.skip.checksum does not take effect.

Because, refer tp below code block ;
"setVerifyChecksum(verifyChecksum)" will override "Builder(conf.getShortCircuitConf())".

 

src/main/java/org/apache/hadoop/hdfs/client/impl/BlockReaderFactory.java
{code:java}

    return new BlockReaderLocal.Builder(conf.getShortCircuitConf()).
        setFilename(fileName).
        setBlock(block).
        setStartOffset(startOffset).
        setShortCircuitReplica(info.getReplica()).
        setVerifyChecksum(verifyChecksum).
        setCachingStrategy(cachingStrategy).
        setStorageType(storageType).
        build();
  }
 {code}
