ambari 安装Hortonworks HDP 时在检测host时异常。 The following hosts have Transparent Huge Pages (THP) enabled。THP should be disabled to avoid potential Hadoop performance issues. 解决办法,在Linux下执行： echo never > /sys/kernel/mm/redhat_transparent_hugepage/defrag echo never > /sys/kernel/mm/redhat_transparent_hugepage/enabled echo never > /sys/kernel/mm/transparent_hugepage/enabled echo never > /sys/kernel/mm/transparent_hugepage/defrag (责任编辑：IT) |
