最近，我的团队正在cdh上使用hbase indexer将hbase表列索引到solr。当我们部署hbase indexer服务器（称为键值存储索引器）并开始测试时。我们发现一种情况，当我们频繁地将数据放入hbase（我们使用的是apache phoenix，hbase之上的一个sql层）时，hbase indexer进程会自动退出，我们检查了日志，发现zookeeper session的错误日志过期如下：

软件环境是：
cdh5.4型
hbase1.0版
Phoenix4.6
hbase索引器（hbase-solr-1.5-cdh5.4.2）
hbase indexer的java堆大小配置为1gb。
有人遇到这种情况吗？
