Subject ask help for hsql conflict problem.
Date Tue, 29 Sep 2009 23:58:30 GMT
Hi there,

    When I have hadoop running (version 0.20.0, Pseudo-Distributed 
Mode), I can not start my own java application. The exception complains 
that 'java.sql.SQLException: failed to connect to url 
"jdbc:hsqldb:hsql://localhost/hsqldb". I have to stop hadoop to start my 
own java application. Both my application and hadoop use hsqldb. Does 
anyone know why and can help me out of this problem?  Or tell me where 
to look for hadoop hsqldb connection implementation, like which kind of 
hsql server mode is used in hadoop and what is the default url of hsqldb 
for hadoop? I looked into org.apache.hadoop.mapred.lib.db package but 
didn't find any clue.

    Thanks in advance!


Best wishes

Sincerely yours

Jianwu Wang
