Re: Cluster crash
This is how it's configured in /etc/security/limits.con on all the
slaves in the cluster:
hadoop           -       nofile          32768
hdfs             -       nofile          32768
hbase            -       nofile          32768
hadoop           -       nproc           32000
hdfs           -       nproc           32000
hbase           -       nproc           32000

When hbase is loading it prints:
ulimit -n 32768
-eran
