I use Hbase0.94 and CDH4. There are 25729 tcp connections in one machine,example: hadoop@apayhbs081 ~ $ netstat -a | wc -l 25729
The linux configration is :
soft core 0
hard rss 10000
hard nproc 20
soft nproc 20
hard nproc 50
hard nproc 0
maxlogins 4
nproc 20480
nofile 204800
When there are 25729 tcp connections in one machine, the datanode is very
slow.
How can I resolve the question?
