我在网上看到一个spark读取hbase的例子(地址http://blog.csdn.net/fighting_one_piece/article/details/38437647),然后想自己试一下,结果报以下错误ERROR mapreduce.TableInputFormatBase (TableInputFormatBase.java:getSplits(191)) - Cannot resolve the host name for TSlave1.Hadoop/192.168.69.123 because of javax.naming.NameNotFoundException: DNS name not found [response code 3]; remaining name '123.69.168.192.in-addr.arpa',我的hosts已经配置好了,可是为什么还是无法解析呢,求大神帮忙
