HDFS文件追加append里的坑

org.apache.hadoop.ipc.RemoteException: Failed to APPEND_FILE /apps/hive/warehouse/ods.db/phone/phone.txt for DFSClient_NONMAPREDUCE_1742740607_1 on 172.17.0.4 because
DFSClient_NONMAPREDUCE_1742740607_1 is already the current lease holder.

原因：追加的文件被打开流被打开，然后又追加造成的。



未等fs.create关闭



将fs.append移到fs.create之后即可
