-------------------------------------
Summary: BASH tab completion doesn't look in PATH, assumes path to
executable is specified
Key: HADOOP-8795
URL: https://issues.apache.org/jira/browse/HADOOP-8795
Project: Hadoop Common
Issue Type: Bug
Reporter: Sean Mackrory
Attachments: HADOOP-8795.patch
bash-tab-completion/hadoop.sh checks that the first token in the command is an
existing, executable file - which assumes that the path to the hadoop
executable is specified (or that it's in the working directory). If the
executable is somewhere else in PATH, tab completion will not work.
I propose that the first token be passed through 'which' so that any
executables in the path also get detected. I've tested that this technique will
work in the event that relative and absolute paths are used as well.
