hdfs cache
I use hadoop-2.4, I want use the hdfs cache function.
I use "ulimit -l 32212254720" linux command to set size of max locked
memory, but there is below error:
ulimit -l 322
-bash: ulimit: max locked memory: cannot modify limit: Operation not
permitted
How can I set size of max locked memory?
Thanks,
LiuLei

Hi, I think you should check the followings:
* The setting is already written to /etc/security/limits.conf.
* The command is executed by root user.
* If you use sshd to connect the server and execute the command, you
should make sure you have "UsePAM yes" in /etc/ssh/sshd_config and
restart sshd once again.
