Linux文件柄和进程限制数

If you are on Ubuntu you will need to make the following changes:

In the file /etc/security/limits.conf add a line like:

 

 hadoop - nofile 32768

 

Replace hadoop with whatever user is running Hadoop and HBase. If you have separate users, you will need 2 entries, one for each user. In the same file set nproc hard and soft limits. For example:

hadoop soft/hard nproc 32000

 

In the file /etc/pam.d/common-session   or  /etc/pam.d/login  add as the last line in the file:

 

session required  pam_limits.so

 

Otherwise the changes in /etc/security/limits.conf won't be applied.

Don't forget to log out and back in again for the changes to take effect!
