HBase的批量get的问题

Question

List<Get> list = new ArrayList<Get>();
for (int i = 0; i < 38000; ++i) {
	Get get = new Get(Bytes.toBytes(1));
	get.setCacheBlocks(false);
	get.addFamily(CURDService.INFO_FAMILY);
	list.add(get);
}
		
hashIdTable.exists(list);

以上是测试代码，表是空的，执行了exists就卡住了，日志显示会不断的重试，把38000调小一点就可以返回了，请问是什么回事呢？求助。下面是重试的日志：

是跟hbase中blocksize大小的设置有关吗
