Subject [jira] [Updated] (HDFS-3100) failed to append data using webhdfs
Date Thu, 15 Mar 2012 20:22:38 GMT

     [ https://issues.apache.org/jira/browse/HDFS-3100?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Tsz Wo (Nicholas), SZE updated HDFS-3100:
-----------------------------------------

    Attachment: testAppend.patch

Unfortunately, this is not specific to WebHDFS.  HDFS also fails with the test.

testAppend.patch: unit tests similar to Zhanwei's script.

>                 Key: HDFS-3100
>                 URL: https://issues.apache.org/jira/browse/HDFS-3100
>             Project: Hadoop HDFS
>          Issue Type: Bug
>          Components: data-node
>    Affects Versions: 0.23.1
>            Reporter: Zhanwei.Wang
>            Assignee: Tsz Wo (Nicholas), SZE
>         Attachments: hadoop-wangzw-datanode-ubuntu.log, hadoop-wangzw-namenode-ubuntu.log,
test.sh, testAppend.patch

> STEP:
> 1, deploy a single node hdfs  0.23.1 cluster and configure hdfs as:
> A) enable webhdfs
> B) enable append
> C) disable permissions
> 2, start hdfs
> 3, run the test script as attached
> RESULT:
> expected: a file named testFile should be created and populated with 32K * 5000 zeros,
HDFS should be OK.
> I got: script cannot be finished, file has been created but not be populated as expected,
actually append operation failed.
> Datanode log shows that, blockscaner report a bad replica and nanenode decide to delete
it. Since it is a single node cluster, append fail. It makes no sense that the script failed
every time.
> Datanode and Namenode logs are attached.
