Runping Qi commented on HADOOP-163: ----------------------------------- Exiting is an option. However, the datanode may still be able to read, thus to serve the existing blocks. > If a DFS datanode cannot write onto its file system. it should tell the name > node not to assign new blocks to it. > ----------------------------------------------------------------------------------------------------------------- > > Key: HADOOP-163 > URL: http://issues.apache.org/jira/browse/HADOOP-163 > Project: Hadoop > Type: Bug > Reporter: Runping Qi > > I observed that sometime, if a file of a data node is not mounted properly, > it may not be writable. In this case, any data writes will fail. The name > node should stop assigning new blocks to that data node. The webpage should > show that node is in an abnormal state. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
