下載Tomcat日誌檔案 runtime_info.log檢視資訊：
[WARN ][19-01-11 18:07:19][http-nio-8080-exec-3][*]Exception encountered while connecting to the server : java.lang.IllegalArgumentException: Server has invalid Kerberos principal: hdfs/[email protected] [WARN ][19-01-11 18:07:19][http-nio-8080-exec-3][*]Exception while invoking class org.apache.hadoop.hdfs.protocolPB.ClientNamenodeProtocolTranslatorPB.getFileInfo over svldl043.csvw.com/10.122.3.61:8020.

同樣程式碼部署到測試環境是OK的，初步判斷是叢集解析問題
#namenode
10.122.3.60 test042.lhx.com
10.122.3.61 test043.lhx.com
10.122.3.62 test044.lhx.com
10.122.3.63 test045.lhx.com
把叢集IP對映配置到Tomcat伺服器中即可。
