我的Java路上那些事儿

最近工作中用到hadoop集群
由于刚开始使用 会出很多问题 经常会得启会删除日志会改配置
但是删除日志 是一件很麻烦的事  集群节点越多 删除日志 越累
索性写一个脚本来删除日志
通过ssh到各个节点  使用这个脚本前提是已经配置ssh无密码登录

dir=$1
case $1 in
hadoop)
 echo "will delete hadoop cluster logs ...."
 rm -rf /usr/hadoop/hadoop-1.0.1/logs/*
 echo "delete hadoop master logs done "
 

 for slave in $(cat /usr/hadoop/hadoop-1.0.1/conf/slaves);do
   echo "delete $slave hadoop logs"
   ssh $slave "rm -rf /usr/hadoop/hadoop-1.0.1/logs/*"
 done
 echo "delete hadoop cluster logs done ..."
 ;;

hbase)
  echo "will delete hbase cluster logs ...."
  rm -rf /usr/hadoop/hbase-0.92.1/logs/*
  echo "delete master hbase logs...."

  for hslave in $(cat /usr/hadoop/hbase-0.92.1/conf/regionservers);do
    echo "delete $hslave hbase logs "
    ssh $hslave "rm -rf /usr/hadoop/hbase-0.92.1/logs/*"
  done
  echo "delete hbase cluster logs done ...."
  ;;

*)
  echo "usage params : {hadoop|hbase} "
