Subject problem to write on HDFS
Date Mon, 14 Mar 2011 17:48:51 GMT
Hello ...

I have a servlet on tomcat.. and it open a hdfs and write simple file with a
content of post information.
Well , in first test we had a 14.000 request per second.
My servet start many trads to write on filesystem.

i got this message on tomcat:

Mar 11, 2011 6:00:20 PM org.apache.tomcat.util.net.JIoEndpoint$Acceptor run
SEVERE: Socket accept failed
java.net.SocketException: Too many open files


HDFS is slow to write a file?
How is a better strategy to write on HFDS...

In real aplication we will have a 100.000 request per second to salve in
hdfs.

thanks..
