hbase admin console shows strange region server's name
Hi ,
We are in process of installations hbase 0.90.1.
We compiled source code of hadoop-append and changed it in the
distribution of hbase
We succeeded to run some tests using only hadoop (map/reduce jobs)
but , after starting hbase we see such region server's list :
There are 2 problems
1) we have only 5 servers but it is 6 on the list.
2) instead of hadoop05.infolinks.local we see IP address
(10.11.87.75<http://10.11.87.75:8042/>
).

What could be wrong in our configuration?
P.S just let me know you need more information like logs , configuration
files
Oleg.

Check DNS for this server. 0.90.1 is finicky if forward and backward
resolves disagree.

Hi,
This is the html table we see in the web console admin (the table in the
previous email was corrupted):
Address Start Code Load
10.11.87.75:8042 1299772503946 requests=0, regions=0,
usedHeap=0, maxHeap=0
hadoop01.infolinks.local:8042 1299772504775 requests=0, regions=0,
usedHeap=29, maxHeap=2483
hadoop02.infolinks.local:8042 1299772504711 requests=0, regions=0,
usedHeap=29, maxHeap=2483
hadoop03.infolinks.local:8042 1299772504028 requests=0, regions=1,
usedHeap=33, maxHeap=2483
hadoop04.infolinks.local:8042 1299772499091 requests=0, regions=1,
usedHeap=34, maxHeap=2483
10.11.87.75:8042 1299772503946 requests=0, regions=0,
usedHeap=31, maxHeap=2483
Total:servers: 6 requests=0, regions=2
you can see that the address 10.11.87.75:8042 appears twice and we don't get
the host name but the ip.
Thanks,
Oleg
