--------------------------------------
Summary: APPEND API call is different in HTTPFS and NameNode REST
Key: HDFS-12654
URL: https://issues.apache.org/jira/browse/HDFS-12654
Project: Hadoop HDFS
Issue Type: Improvement
Components: hdfs, httpfs, namenode
Affects Versions: 3.0.0-beta1, 2.8.0, 2.7.0, 2.6.0
Reporter: Andras Czesznak
The APPEND REST API call behaves differently in the NameNode REST and the
HTTPFS codes. The NameNode version creates the target file the new data being
appended to if it does not exist at the time of the call issued. The HTTPFS
version assumes the target file exists when APPEND is called and can append
only the new data but does not create the target file it doesn't exist.
The two implementations should be standardized, preferably the HTTPFS version
should be modified to execute an implicit CREATE if the target file does not
exist.
