Stephen Chu commented on HADOOP-11277: -------------------------------------- Yeah, in typical code 1 == true and 0 == false, but the Hadoop commands follow the unix exit code conventions, where 0 means the command was successful and non-zero means otherwise. In this scenario, when we run {{hadoop fs -test -e}} on a file that exists, then the exit code is 0, meaning that the existence test ran successfully. > hdfs dfs test command "returning 0 if true." instead of what should be > "returning 1 if true." > ---------------------------------------------------------------------------------------------- > > Key: HADOOP-11277 > URL: https://issues.apache.org/jira/browse/HADOOP-11277 > Project: Hadoop Common > Issue Type: Bug > Components: fs > Affects Versions: 2.5.0 > Reporter: DeepakVohra > > The CDH5 File System (FS) shell commands documentation has an error.
