Subject HDFS java client connect retry count
Date Tue, 17 Aug 2010 22:49:56 GMT
Hi,
I have a java HDFS client which connects to a production cluster and gets data. 
On our staging environment we see that since it cannot connect to the namenode 
(expected) it keeps retrying for 45 times. I am looking for a way to set the 
retry count to much much lower.

This is what we see in server logs:

2010-08-17 15:15:06,973 INFO  [Client] Retrying connect to server: 
xxxx.yyyy.zzzz.com/192.168.1.11:9000. Already tried 0 time(s).
2010-08-17 15:15:27,979 INFO  [Client] Retrying connect to 
server: xxxx.yyyy.zzzz.com/192.168.1.11:9000. Already tried 1 time(s).
2010-08-17 15:15:48,984 INFO  [Client] Retrying connect to 
server: xxxx.yyyy.zzzz.com/192.168.1.11:9000. Already tried 2 time(s).
2010-08-17 15:16:09,989 INFO  [Client] Retrying connect to 
server: xxxx.yyyy.zzzz.com/192.168.1.11:9000. Already tried 3 time(s).

server: xxxx.yyyy.zzzz.com/192.168.1.11:9000. Already tried 44 time(s).

I have tried the client config 
job.set("ipc.client.connect.max.retries", "5");

which doesn't seem to work.

Where is this 45 reties coming from? 

Thanks in advance. -Ayon
