Subject [jira] Created: (HADOOP-3067) DFSInputStream 'pread' does not close its sockets
Date Fri, 21 Mar 2008 20:33:24 GMT
DFSInputStream 'pread' does not close its sockets
-------------------------------------------------

                 Key: HADOOP-3067
                 URL: https://issues.apache.org/jira/browse/HADOOP-3067
             Project: Hadoop Core
          Issue Type: Bug
          Components: dfs
            Reporter: Raghu Angadi
            Assignee: Raghu Angadi
             Fix For: 0.17.0



{{DFSInputStream.read(int, buffer)}} does not close the sockets it opens. Main reason this
problem did not show up till now is that pread interface is not used much.

TestCrcCorruption failure first reported in HADOOP-2902 is caused by this bug. Hadoop 0.17
uses more file descriptors for each thread waiting on socket io. Since client does not close
sockets, it leaves a lot of DataNode threads waiting in the unit test.
