[大数据]Zookeeper节点下的子节点数过多，rmr删除报错

修改ZKCli.sh，加上"-Djute.maxbuffer=49107800"$JAVA "-Dzookeeper.log.dir=${ZOO_LOG_DIR}" "-Dzookeeper.root.logger=${ZOO_LOG4J_PROP}" \
?"-Djute.maxbuffer=49107800" -cp "$CLASSPATH" $CLIENT_JVMFLAGS $JVMFLAGS \ 
?org.apache.zookeeper.ZooKeeperMain "$@"

改完后rmr /xxx

如果还不行，写代码解决。参考代码如下

package com.xxx.server;

import com.kingdee.bos.qing.dfs.common.util.ZKClientUtil;
import java.io.PrintStream;
import java.util.ArrayList;
import java.util.List;
import org.apache.curator.framework.CuratorFramework;
import org.apache.curator.framework.api.DeleteBuilder;
import org.apache.curator.framework.api.GetChildrenBuilder;

public class RMRLock
{
  static
  {
    System.setProperty("zk.server.url", "127.0.0.1:2181");
    System.setProperty("jute.maxbuffer", "2097152000");
  }
  
  static CuratorFramework zkClient = ZKClientUtil.getClient();
  public static List<String> zkNodes = new ArrayList();
  
  public static void main(String[] args)
  {
    try
    {
      System.out.println("rmr lock start");
      rmrNode("/Lock");
    }
    catch (Exception e)
    {
      e.printStackTrace();
    }
  }
  
  public static void rmrNode(String parentNode)
  {
    try
    {
      List<String> tmpList = (List)zkClient.getChildren().forPath(parentNode);
      for (String tmp : tmpList)
      {
        String childNode = parentNode + "/" + tmp;
        zkClient.delete().forPath(childNode);
      }
    }
    catch (Exception e)
    {
      e.printStackTrace();
    }
  }
}

java -classpath /srv/xxx/libs/*:/srv/xxx/conf/ com.xxx.server.RMRLock
