-----------------------------------------
Summary: `hadoop classpath` behaviour different from previous
releases
Key: HADOOP-11777
URL: https://issues.apache.org/jira/browse/HADOOP-11777
Project: Hadoop Common
Issue Type: Bug
Affects Versions: 2.6.0
Reporter: Swapnil Daingade
Assignee: Swapnil Daingade
In 2.6 doing a `hadoop classpath` returns the following
classpath [--glob|--jar <path>|-h|--help] :
Prints the classpath needed to get the Hadoop jar and the required
libraries.
Options:
--glob expand wildcards
--jar <path> write classpath as manifest in jar named <path>
-h, --help print help
This is different from earlier releases.
However, passing any argument to the command will return the classpath as
earlier
E.g. `hadoop classpath foo`
It would be nice to preserve the original behaviour for scripts that read the
classpath using this command.
The fix seems to be a one line change in
hadoop-common-project/hadoop-common/src/main/bin/hadoop
