cannot start cassandra. Fail setting ulimit

Question

I installed cassandra and tried starting service but stuck with below error. May I know What value I should change? Thanks for your time.

#service dse start
Starting DSE daemon : dse
DSE daemon starting with just Cassandra enabled (edit /etc/default/dse to enable)
Fail setting `ulimit '-p' '8'`: /etc/init.d/dse: line 430: ulimit: pipe size: cannot modify limit: Invalid argument

 /etc/init.d/dse file contains below info

copy_limits(){
    # Use CASSANDRA_USER as a default argument
    local user=${1:-${CASSANDRA_USER}}

    # Since /bin/sh has a limited `ulimit` and `prlimit` from 'utils-linux' is
    #   not well spread, we use `for` as an alternative
    local c
    for p in -t -f -d -s -c -m -l -p -n; do
        local v="$( su - "$user" -s /bin/sh -c "ulimit $p" 2>/dev/null )"
==>line 430 in error ***** :       ulimit $p $v 2>&1 | \
            while read err; do
                log_message "Fail setting \`ulimit '$p' '$v'\`: $err"
            done
    done
}

The node should be UP regardless of the error message. You can verify this by running sudo service dse status or nodetool ring.

If that does not help, a workaround would be to edit /etc/init.d/dse and remove the -p flag in the for loop that you're seeing in the error message (for p in -t -f -d -s -c -m -l -n; do)
