             Summary: LogAggregationIndexedFileController - Can not get log 
meta from the log 
                 Key: YARN-8106
                 URL: https://issues.apache.org/jira/browse/YARN-8106
             Project: Hadoop YARN
          Issue Type: Bug
          Components: log-aggregation
    Affects Versions: 2.7.3
            Reporter: Prabhu Joseph
            Assignee: Prabhu Joseph


yarn logs command fails with below error message. Found  
LogAggregationIndexedFileController uses read() to read the contents of 
remoteLog into byte array which sometimes does not read full contents and so 
actual bytes read is not same as offset leading to IOException. readFully() can 
be used.

{code}
WARN ifile.LogAggregationIndexedFileController: Can not get log meta from the 
log 
Error on loading log meta from 

 if (actual != offset) {
        throw new IOException("Error on loading log meta from "
            + remoteLogPath);
      }
{code}
