Date Mon, 01 Aug 2016 09:15:20 GMT
Jiahongchao created HDFS-10709:
----------------------------------

             Summary: hdfs shell du command not match OS du command
                 Key: HDFS-10709
                 URL: https://issues.apache.org/jira/browse/HDFS-10709
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: fs
    Affects Versions: 2.6.0
         Environment: centos 6.7,jdk 1.7
            Reporter: Jiahongchao
            Priority: Minor


I got files created by solr on HDFS, but the size is different when using HDFS du and centos
du.
[apd@dev186 ~]$ hdfs dfs -du /solr/fileSizeTest/core_node1/data/tlog
46  402653184  /solr/fileSizeTest/core_node1/data/tlog/tlog.0000000000000000002
[apd@dev186 ~]$ hdfs dfs -ls /solr/fileSizeTest/core_node1/data/tlog
Found 1 items
-rw-r--r--   3 solr solr         46 2016-08-01 13:18 /solr/fileSizeTest/core_node1/data/tlog/tlog.0000000000000000002

after download this file using get,
[apd@dev186 ~]$ ll -h  tlog.0000000000000000002 
-rw-r--r-- 1 apd apd 8.5M Aug  1 15:48 tlog.0000000000000000002

so what's dfhs dfs's du?And why the two values are so different? 46  vs 402653184 ?
