Subject [jira] Commented: (MAPREDUCE-2301) TestDataDrivenDBInputFormat fails if port 9001 is occupied
Date Fri, 04 Feb 2011 22:06:30 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2301?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12990769#comment-12990769
] 

Aaron Kimball commented on MAPREDUCE-2301:
------------------------------------------

+1 Changes look reasonable.

FWIW, I don't think this is going to entirely solve your problem. {{TestDBJob}} should fail
for the exact same reason -- it runs the job specified in {{DBCountPageView.java}} under {{src/examples}}.
So you might need to parameterize the {{DB_URL}} in that process as well and make embedded
server hosting conditional on its value. (If TestDDDBIF fails and TestDBJob doesn't... that's
something else worth pondering.)

> If you have any process listening on port 9001 (the default hsqldb port) then TestDataDrivenDBInputFormat
will fail with:
> Connection is broken: java.io.EOFException
> java.sql.SQLException: Connection is broken: java.io.EOFException
>         at org.hsqldb.jdbc.Util.sqlException(Unknown Source)
> in the logs you see:
> [Server@42704baa]: [Thread[HSQLDB Server @42704baa,5,main]]: run()/openServerSocket():
> java.net.BindException: Address already in use
