我想通过API将数据从平面文件加载到Hbase。但我得到以下错误 ======== ================================================ java在有机.lang.NumberFormatException.forInputString在java.lang.Integer.parseInt(Integer.java:492) (NumberFormatException.java:65) 在java.lang.Integer.parseInt(Integer.java:527) 。 apache.hadoop.hbase.HServerAddress。(HServerAddress.java:63) at org.apache.hadoop.hbase.MasterAddressTracker.getMasterAddress(MasterAddressTracker.java:63) at org.apache.hadoop.hbase.client.HConnectionManager $ HConnectionImplementati on.getMaster(HConnectionManager.java:354) 在org.apache.hadoop.hbase.client.HBaseAdmin。(HBaseAdmin.java:94) 在Hbase.readFromFile.main(readFromFile.java:16)Hbase:需要合适的jar文件cloudera-quickstart-vm-5.4.2-0

请让我知道我们是否需要添加..我现在用的Cloudera Cloudera的,快速入门-VM-5.4.2-0
感谢任何合适的罐子, VJ
